Intel Wired LAN Driver Updates 2015-03-07
This series contains updates to i40e and i40evf only.
Most notably, Greg provides the patch to remove the dreaded configfs
changes in the driver.
Shannon cleans up a sparse warning by simply straighting out the code
so it is less convoluted. Fixes an issue where the vector allocation
was trying too hard to save vectors for VMDq, to the point of not giving
the PF enough when in a tight situation, such as an NPAR partition.
Changed the driver to make sure that the PF will get all the queues and
vectors it wants to fill out its destiny. Cleans up reporting to only
print the port and VEB stats if it is the first partition of a
multiplexed port.
Catherine cleans up some duplicated code by simply removing the duplicate
code.
Kamil cleans up the driver by removing an un-needed endian conversion
because it is already done by a register read function.
Jesse fixes a variable width of a datatype, where a u16 should have been
a u32. Also cleans up debug_read_register() to resolve some sparse
warnings. Updates the driver to use prefetch() to get the next Tx
descriptor, like in ixgbe, to improve performance.
Akeem moves around code to enable/disable loopback so that other non-SRIOV
supported driver functions can take advantage of the changes.
Anjali cleans up the logging for adding/deleting FD-SB filters, since
ethtool shows all the filters on an interface. Updates the driver to
use l4_tunnel type generically to keep code flow simple. Simplifies
the RSS code since the driver initializes the rss_size_max in sw_init.

In preparation for supporting multiple Rx queues:
1. Move the initialization of priv->num_rx_bds, priv->rx_bds, and
priv->rx_cbs from bcmgenet_init_rx_ring() to bcmgenet_init_dma()
since they are not specific to a single Rx queue. Mimics the Tx
init model where priv->num_tx_bds, priv->tx_bds, and priv->tx_cbs
are initialized in bcmgenet_init_dma().
2. Program DMA_MBUF_DONE_THRESH = 1 so that future Rx queues Q0-Q15
will get per-packet Rx interrupt.
3. Group DMA_START_ADDR, RDMA_READ_PTR, RDMA_WRITE_PTR, and DMA_END_ADDR
initialization together. Mimics the Tx init model.
4. There is 1-to-1 mapping between RxCBs and RxBDs.
Precalculate RxCB->bd_addr so that it can be used in the future.

macb and at91_ether drivers can be compiled as modules, but the at91_ether
driver use some functions and variables defined in the macb one, thus
creating a dependency on the macb driver.
Since these drivers are sharing the same logic we can easily merge
at91_ether into macb.
In order to factorize common probing logic we've added an ->init() function
to struct macb_config (the structure associated with the compatible
string), and moved macb specific init code from macb_probe to macb_init.

Most of the functions from the Common Clk Framework handle NULL pointer as
input argument.
Since the TX clock is optional, we now set tx_clk to NULL value
instead of ERR_PTR(-ENOENT) when this clock is not available. This simplifies
the clock management and avoid the need to test tx_clk value.

Since GLQF_FDCNT_0 register now has the right offset, use it to simplify our
FD flush flow.
If the filter add error happens to be for SB we just auto disable SB.
If filter error happens to be for ATR, auto disable ATR and mark
the state to FD_FLUSH_REQUESTED. Which gets cleared when flush completes.
If we are entering flush too quickly (< 30 seconds) and we have quite
a few SB rules, its time to disable ATR for good. Since SB + ATR rules
is most likely making the FD table unstable.
ATR can be re-enabled by turning ntuple off (ethtool -K ntuple off)
and will remain off after turning ntuple on till it gets unstable again.

sure that the PF will get all the queues and vectors it wants to fill

it simply gets whatever is left after the PF, FCoE, and FD sideband get
what they want.
Additionally, the calculations for the reservations were harder to follow
than necessary, so I've made it more straight forward.

Intel Wired LAN Driver Updates 2015-03-06
This series contains updates to e1000, e1000e and igb.
Yanir provides updates to e1000e based on the patches provided by John
Linville. First updates the code comment to better describe the changes
and the impact on the driver. Second removed calls to ioremap/unmap for
i219 since this is only relevant to older hardware only. Starting with
i219, the NVM will not be mapped to its one BAR but to a address region
in another bar.
Alex Duyck provides two fixes for igb, first fixes a compile warning
where a variable may be used uninitialized, so Alex initializes it.
Second fixes an issue where all of the pin register values were having
to be pushed onto the stack each time the function was called, so to
avoid this, Alex made them static const so that they should only need
to be allocated once and we can avoid all the instructions to get them
onto the stack.
Eliezer found an issue in e1000 where we needed to be calling
netif_carrier_off earlier in the down() to prevent the stack from
queuing more packets to the interface.
Sabrina Dubroca resolved a potential race condition by adding a
dummy allocator. There was a race condition between e1000_change_mtu()
cleanups and netpoll, when changing the MTU across jumbo sizes.

There is a race condition between e1000_change_mtu's cleanups and
netpoll, when we change the MTU across jumbo size:
Changing MTU frees all the rx buffers:
e1000_change_mtu -> e1000_down -> e1000_clean_all_rx_rings ->
e1000_clean_rx_ring
Then, close to the end of e1000_change_mtu:
pr_info -> ... -> netpoll_poll_dev -> e1000_clean ->
e1000_clean_rx_irq -> e1000_alloc_rx_buffers -> e1000_alloc_frag
And when we come back to do the rest of the MTU change:
e1000_up -> e1000_configure -> e1000_configure_rx ->
e1000_alloc_jumbo_rx_buffers
alloc_jumbo finds the buffers already != NULL, since data (shared with
page in e1000_rx_buffer->rxbuf) has been re-alloc'd, but it's garbage,
or at least not what is expected when in jumbo state.
This results in an unusable adapter (packets don't get through), and a
NULL pointer dereference on the next call to e1000_clean_rx_ring
(other mtu change, link down, shutdown):
BUG: unable to handle kernel NULL pointer dereference at (null)

By setting the allocator to a dummy version, netpoll can't mess up our
rx buffers. The allocator is set back to a sane value in
e1000_configure_rx.

When bringing down an interface netif_carrier_off() should be
one the first things we do, since this will prevent the stack
from queuing more packets to this interface.
This operation is very fast, and should make the device behave
much nicer when trying to bring down an interface under load.
Also, this would Do The Right Thing (TM) if this device has some

The driver implements ndo_switch_fib_ipv4_add/del ops to add/del/mod IPv4
routes to/from switchdev device. Once a route is added to the device, and the
route's nexthops are resolved to neighbor MAC address, the device will forward
matching pkts rather than the kernel. This offloads the L3 forwarding path
from the kernel to the device. Note that control and management planes are
still mananged by Linux; only the data plane is offloaded. Standard routing
control protocols such as OSPF and BGP run on Linux and manage the kernel's FIB
via standard rtm netlink msgs...nothing changes here.
A new hash table is added to rocker to track neighbors. The driver listens for
neighbor updates events using netevent notifier NETEVENT_NEIGH_UPDATE. Any ARP
table updates for ports on this device are recorded in this table. Routes
installed to the device with nexthops that reference neighbors in this table
are "qualified". In the case of a route with nexthops not resolved in the
table, the kernel is asked to resolve the nexthop.
The driver uses fib_info->fib_priority for the priority field in rocker's
unicast routing table.
The device can only forward to pkts matching route dst to resolved nexthops.
Currently, the device only supports single-path routes (i.e. routes with one
nexthop). Equal Cost Multipath (ECMP) route support will be added in followup
patches.
This patch is driver support for unicast IPv4 routing only. Followup patches
will add driver and infrastructure for IPv6 routing and multicast routing.

This series contains updates to i40e only.
Greg provides fixes for the NPAR transmit scheduler where the driver
initialization caused the BW configurations to not take effect, so use
a BW configuration read and write back to "kick" the transmit scheduler
into action. Fixes the ethtool offline test, where we were not actually
taking the device offline before doing the testing.
Matt modifies the get and set LED functions so they ignore activity LEDs
since we are required to blink the link LEDs only.
Neerav provides a workaround for whenever a DCBX configuration is changed,
where the firmware doe not set the operational status bit of the
application TLV status as returned from the "Get CEE DCBX Oper Cfg" admin
queue command. So remove the check for the operational and sync bits of
the application TLV status until a firmware fix is provided.
Shannon changes the driver to grab the NVM devstarter version and not
the image version, since it is the more useful version and is what
should be displayed. Moves the IRQ tracking setup and tear down into
the same routines that do the IRQ setup and tear down. This keeps
like activities together and allows us to track exactly the number
of vectors reserved from the OS, which may be fewer than are available
from the hardware.
Jesse provides a fix to use a more portable sign extension by replacing
0xffff.... with ~(u64)0 or ~(u32)0. Also fixes XPS mask when resetting,
where the driver would accidentally clear the XPS mask for all queues
back to 0. This caused higher CPU utilization and had some other
performance impacts for transmit tests. Cleans up some whitespace
formatting.
Catherine provides a fix where some firmware versions are incorrectly
reporting a breakout cable as PHY type 0x3 when it should be 0x16
(I40E_PHY_TYPE_10GBASE_SFPP_CU). Adds the 10G and 40G AOC PHY types
to the case statement in get_media_type and ethtool get_settings so
that the correct information gets reported back to the user.
Anjali provides IOREMAP changes for future device support, where we
do not want to map the whole CSR space since some of it is mapped by
other drivers with different mapping methods.
Mitch changes the i40e driver to not "spam" the system log with
messages about VF VSI when VFs are created and when they are reset to
reduce user annoyance.

The PF driver spams the system log with messages about VF VSI when VFs
are created, as well as each time they are reset. This is annoying, and
the information isn't even useful most of the time.
Remove this message to reduce user annoyance.

Move the IRQ tracking setup and teardown into the same routines that
do the IRQ setup and teardown. This keeps like activities together and
allows us to track exactly the number of vectors reserved from the OS,
which may be fewer than are available from the HW.

For future device support we do not want to map the whole CSR space since some
of it is mapped by other drivers with different mapping methods.
Note: As a side effect, the flash region (if exposed through the memory map)
gets unmapped too since it follows the future use region.

Fix some double blank lines and un-split a function declaration that all
fits on one line. Also make i40e_get_priv_flags static.

Add the 10G and 40G AOC PHY types to the case statement in get_media_type
and ethtool get_settings so that the correct information gets reported
back to the user.
