net: thunderx: add support for PTP clock
This series adds support for IEEE 1588 Precision Time Protocol
to Cavium ethernet driver.
The first patch adds support for the Precision Time Protocol Clocks and
Timestamping coprocessor (PTP) found on Cavium processors.
It registers a new PTP clock in the PTP core and provides functions
to use the counter in BGX, TNS, GTI, and NIC blocks.
The second patch introduces support for the PTP protocol to the
Cavium ThunderX ethernet driver.

- check if ptp_clock_register() returns NULL (Richard Cochran)
- fix doc comment for cavium_ptp_enable() (Richard Cochran)
- fix a function call formatting; use defined constant (Richard Cochran)
- add comments for `tx_ptp_skbs` and `ptp_skb` (Richard Cochran)

This adds timestamping support for both receive and transmit
paths. On the receive side no filters are supported i.e either
all pkts will get a timestamp appended infront of the packet or none.
On the transmit side HW doesn't support timestamp insertion but
only generates a separate CQE with transmitted packet's timestamp.
Also HW supports only one packet at a time for timestamping on the

The check in sctp_sockaddr_af is not robust enough to forbid binding a
v4mapped v6 addr on a v4 socket.
The worse thing is that v4 socket's bind_verify would not convert this
v4mapped v6 addr to a v4 addr. syzbot even reported a crash as the v4
socket bound a v6 addr.
This patch is to fix it by doing the common sa.sa_family check first,
then AF_INET check for v4mapped v6 addrs.

After commit cea0cc80a6 ("sctp: use the right sk after waking up from

peeled off in sctp_wait_for_sndbuf.
However, the asoc's new sk could be already closed elsewhere, as it's in
the sendmsg context of the old sk that can't avoid the new sk's closing.
If the sk's last one refcnt is held by this asoc, later on after putting
this asoc, the new sk will be freed, while under it's own lock.
This patch is to revert that commit, but fix the old issue by returning
error under the old sk's lock.

devlink: Add support for resource abstraction
Arkadi says:
Many of the ASIC's internal resources are limited and are shared between
several hardware procedures. For example, unified hash-based memory can
be used for many lookup purposes, like FDB and LPM. In many cases the user
can provide a partitioning scheme for such a resource in order to perform
fine tuning for his application. In such cases performing driver reload is
needed for the changes to take place, thus this patchset also adds support
for hot reload.
Such an abstraction can be coupled with devlink's dpipe interface, which
models the ASIC's pipeline as a graph of match/action tables. By modeling
the hardware resource object, and by coupling it to several dpipe tables,
further visibility can be achieved in order to debug ASIC-wide issues.
The proposed interface will provide the user the ability to understand the
limitations of the hardware, and receive notification regarding its occupancy.
Furthermore, monitoring the resource occupancy can be done in real-time and
can be useful in many cases.

Due to architecture limitations, the IBM VNIC client driver is unable
to perform MAC address changes unless the device has "logged in" to
its backing device. Currently, pending MAC changes are handled before
login, resulting in an error and failure to change the MAC address.
Moving that chunk to the end of the ibmvnic_login function, when we are
sure that it was successful, fixes that.
The MAC address can be changed when the device is up or down, so
only check if the device is in a "PROBED" state before setting the
MAC address.

ipv4: Make neigh lookup keys for loopback/point-to-point devices be INADDR_ANY
This used to be the previous behavior in older kernels but became broken in
a263b30936 (ipv4: Make neigh lookups directly in output packet path)
and then later removed because it was broken in 0bb4087cbe (ipv4: Fix neigh
lookup keying over loopback/point-to-point devices)
Not having this results in there being an arp entry for every remote ip
address that the device talks to. Given a fairly active device it can
cause the arp table to become huge and/or having to add/purge large number
of entires to keep within table size thresholds.

Map all lookup neigh keys to INADDR_ANY for loopback/point-to-point devices
to avoid making an entry for every remote ip the device needs to talk to.
This used the be the old behavior but became broken in a263b30936
(ipv4: Make neigh lookups directly in output packet path) and later removed
in 0bb4087cbe (ipv4: Fix neigh lookup keying over loopback/point-to-point
devices) because it was broken.

Use n->primary_key instead of pkey to account for the possibility that a neigh
constructor function may have modified the primary_key value.

ARSTR is always located at the start of the TSU register region, thus
using add_reg() instead of add_tsu_reg() in __sh_eth_get_regs() to dump it
causes EDMR or EDSR (depending on the register layout) to be dumped instead
of ARSTR. Use the correct condition/macro there...

Here are patches which have been accumulating over the holidays and
after the New Year. Business as usual and nothing special really
standing out.
But what's noteworthy here is that Larry Finger is stepping down as
the rtlwifi maintainer. He has been maintaining rtlwifi since it was
applied back in 2010 in commit 0c8173385e ("rtl8192ce: Add new
driver") and it has been no easy role trying to juggle between the
vendor, demanding upstream community and users. So big thank you to
Larry for all his efforts!

The Gemini ethernet has been around for years as an out-of-tree
patch used with the NAS boxen and routers built on StorLink
SL3512 and SL3516, later Storm Semiconductor, later Cortina
Systems. These ASICs are still being deployed and brand new
off-the-shelf systems using it can easily be acquired.
The full name of the IP block is "Net Engine and Gigabit
Ethernet MAC" commonly just called "GMAC".
The hardware block contains a common TCP Offload Enginer (TOE)
that can be used by both MACs. The current driver does not use
it.

This adds the device tree bindings for the Gemini ethernet
controller. It is pretty straight-forward, using standard
bindings and modelling the two child ports as child devices
under the parent ethernet controller device.

This reverts commit ceaa001a17.
The OVS_TUNNEL_KEY_ATTR_ERSPAN_OPTS attr should be designed
as a nested attribute to support all ERSPAN v1 and v2's fields.
The current attr is a be32 supporting only one field. Thus, this
patch reverts it and later patch will redo it using nested attr.
