c194992cbe skge: fix broken driver
The patch 136d8f377e broke the skge driver.
Note this part of the patch:
+               if (skge_rx_setup(skge, e, nskb, skge->rx_buf_size) < 0) {
+                       dev_kfree_skb(nskb);
+                       goto resubmit;
+               }
+
                pci_unmap_single(skge->hw->pdev,
                                 dma_unmap_addr(e, mapaddr),
                                 dma_unmap_len(e, maplen),
                                 PCI_DMA_FROMDEVICE);
                skb = e->skb;
                prefetch(skb->data);
-               skge_rx_setup(skge, e, nskb, skge->rx_buf_size);

The function skge_rx_setup modifies e->skb to point to the new skb. Thus,
after this change, the new buffer, not the old, is returned to the
networking stack.

This bug is present in kernels 3.11, 3.11.1 and 3.12-rc1. The patch should
be queued for 3.11-stable.

48a3056973 cnic: Fix crash in cnic_bnx2x_service_kcq()
commit 104a43edb2
    cnic: Use CHIP_NUM macros from bnx2x.h

changed the code to use the bnx2x macro NO_FCOE() to determine if FCoE
is supported or not.  There is another place in cnic that is still using
the old method to determine if FCoE is supported or not.  The 2 methods
may not yield the same result after the network interface is brought down
and up.  This will cause the crash as cnic_bnx2x_service_kcq() will access
the uninitialized cp->kcq2.

The fix is to consistently use the same macro CNIC_SUPPORTS_FCOE() which
uses the bnx2x NO_FCOE() macro.  As a follow-up, we can clean up the code
to remove the old method as it is no longer needed.

f78afb3563 bnx2x, cnic, bnx2i, bnx2fc: Fix bnx2i and bnx2fc regressions.
commit b9871bcfd2
    bnx2x: VF RSS support - PF side

changed the configuration of the doorbell HW and it broke iSCSI and FCoE.
We fix this by making compatible changes to the doorbell address in bnx2i
and bnx2fc.  For the userspace driver, we need to pass a modified CID
so that the existing userspace driver will calculate the correct doorbell
address and continue to work.

Ben Hutchings says:

====================
Some bug fixes and future-proofing for the recently added SFC9120
support:

1. Minimal support for the 40G configuration.
2. Disable the incomplete PTP/hardware timestamping support.
3. Reset MAC stats properly after a firmware upgrade.
4. Re-check the datapath firmware capabilities after the controller is
reset.

9900303ec7 bgmac: implement unaligned addressing for DMA rings that support it
This is important patch for new devices that support unaligned
addressing. That devices suffer from the backward-compatibility bug in
DMA engine. In theory we should be able to use old mechanism, but in
practice DMA address seems to be randomly copied into status register
when hardware reaches end of a ring. This breaks reading slot number
from status register and we can't use DMA anymore.

6a391e7bf2 bgmac: fix internal switch initialization
Some devices (BCM4749, BCM5357, BCM53572) have internal switch that
requires initialization. We already have code for this, but because
of the typo in code it was never working. This resulted in network not
working for some routers and possibility of soft-bricking them.

Use correct bit for switch initialization and fix typo in the define.

c3a0dce35a e1000e: fix overrun of PHY RAR array
When copying the MAC RAR registers to PHY there is an error in the
calculation of the rar_entry_count, which causes a write of unknown/
undefined register space in the MAC to unknown/undefined register space in
the PHY.

This patch fixes the overrun with writing to the PHY RAR and also fixes the
ethtool offline register tests so that the correctly addressed registers
have the appropriate bitmasks for R/W and RO bits for affected parts.

Shawn Rader gets credit for finding and fixing the register overrun.

V6: rename Kbuild to Makefile
    rename i40e_mem[set|cpy] to regular memset/memcpy
V5: remove sysfs support from this set, will rearchitect
    changes from community comments
V4: addresses remaining community comments, mostly trivial edits.

V3: many more individual comments addressed, thanks reviewers!  Many
    other changes due to internal review and development.
V2: each patch has individual comments, in general, feedback from the
    list was applied and addressed. Many changes due to internal review
    and coding as well.
V1: initial send

Let me start by saying thanks and we appreciate any time spent by
those of you who review and comment on this new driver, and we will
attempt to address and respond to all issues brought to our attention.

I tried to break the patches up to ease review, but the series should
apply and still be bisectable, as the last patch adds the driver to
the kernel compile with CONFIG_I40E.

This driver is for a brand new bit of silicon that has a different
design than other Intel Ethernet silicon, and therefore needed a new
driver.

The hardware has quite a bit of capability and this driver is only
meant to provide basic functionality at first.  Future patches will
continue to add functionality and bug fixes.

This initial release is very early in the product cycle with the intent
of getting initial support into the kernel before users have the
hardware available to purchase.  A software development manual is not
ready yet but will be available when the hardware ships.

The driver development model and interaction with community submitted
patches *will not be any different* than what we are currently doing
today.  We plan to continue established processes.

An associated i40evf driver has been posted for review.

List of tools we ran in preparation:
way more sparse clean
make W=1, W=2 clean
checkpatch (almost) clean
        total: 1 errors, 4 warnings, 30461 lines checked
        NOTE: Ignored message types: LONG_LINE
        - issues have been addressed and the remainders
          are noise.
codespell clean
smatch (almost) clean with a couple minor warnings
coccicheck clean
namespacecheck clean
allmodconfig clean
ppc64 build clean (untested)

This driver is a team effort, thank you to Joseph Gasparakis,
Shannon Nelson, Anjali Singhai-Jain, Mitch Williams, Neerav
Parikh, Vasu Dev, Kavindya Deegala, Yi Zou, and PJ Waskiewicz.

TODO (known issues)
BQL implementation
finish rtnl_stat64 locking (we have a patch but debugging it)

444fa88ac3 net: tilegx driver: avoid compiler warning
The "id" variable was being incremented in common code, but only
initialized and used in IPv4 code.  We move the increment to the IPv4
code too, and then legitimately use the uninitialized_var() macro to
avoid the gcc 4.6 warning that 'id' may be used uninitialized.
Note that gcc 4.7 does not warn.

996dedbafe bnx2x: avoid atomic allocations during initialization
During initialization bnx2x allocates significant amounts of memory
(for rx data, rx SGEs, TPA pool) using atomic allocations.

I received a report where bnx2x failed to allocate SGEs and it had
to fall back to TPA-less operation.

Let's use GFP_KERNEL allocations during initialization, which runs
in process context. Add gfp_t parameters to functions that are used
both in initialization and in the receive path.

Use an unlikely branch in bnx2x_frag_alloc() to avoid atomic allocation
by netdev_alloc_frag(). The branch is taken several thousands of times
during initialization, but then never more. Note that fp->rx_frag_size
is never greater than PAGE_SIZE, so __get_free_page() can be used here.

a915ccc9f2 sfc: Reinitialise and re-validate datapath caps after MC reboot
After an MC reboot, the datapath may be running a different firmware
variant and have different capabilities.  It is critical that we know
the current capabilities so that we can pass valid flags to
MC_CMD_INIT_EVQ.

e5a2538a48 sfc: Clean up validation of datapath capabilities
Rename efx_ef10_init_capabilities() to the more specific
efx_ef10_init_datapath_caps().

Stop accepting short responses to MC_CMD_GET_CAPABILITIES; we
don't need to support pre-production firmware.

Move the check for RX prefix support from efx_ef10_probe() into
efx_ef10_init_datapath_caps() and use consistent error messages
for missing TSO support and missing RX prefix support.

If the MC reboots then the stats it reports to us will have been
reset.  We need to reset ours to get efx_update_diff_stat() working
properly.

8b59f017e4 sfc: Disable PTP on EF10 until we're ready to handle inline RX timestamps
Unlike Siena where timestamping is provided by a peripheral, EF10
delivers RX timestamps in the packet prefix.  However the driver
doesn't yet support this.

We are also creating a PHC device for each EF10 function, even though
the clock is really shared between all of them.

Disable hardware PTP/timestamping support until it's complete.
