Browsing thru the driver disassembly, I noticed that ARM gcc generated
no code whatsoever for sh_eth_soft_swap() while building a little-endian
kernel -- apparently __LITTLE_ENDIAN__ was not being #define'd, however
it got implicitly #define'd when building with the SH gcc (I could only
find the explicit #define __LITTLE_ENDIAN that was #include'd when building
a little-endian kernel). Luckily, the Ether controller only doing big-
endian DMA is encountered on the early SH771x SoCs only and all ARM SoCs
implement EDMR.DE and thus set 'sh_eth_cpu_data::hw_swap'. But anyway, we
need to fix the #ifdef inside sh_eth_soft_swap() to something that would
work on all architectures...

When offloading mirroring to gretap or ip6gretap netdevices, an 802.1q
bridge is one of the soft devices permissible in the underlay when
resolving the packet path. After the packet path is resolved to a
particular bridge egress device, flags on packet VLAN determine whether
the egressed packet should be tagged.
The current logic however only ever sets the VLAN tag, never suppresses
it. Thus if there's a VLAN netdevice above the bridge that determines
the packet VLAN, that VLAN is never unset, and mirroring is configured
with VLAN tagging.
Fix by setting the packet VLAN on both branches: set to zero (for unset)
when BRIDGE_VLAN_INFO_UNTAGGED, copy the resolved VLAN (e.g. from bridge
PVID) otherwise.

In the case of the VF driver it is supposed to provide a context descriptor
that allows us to provide information about the header offsets inside of
the frame. However in the case of XDP we don't really have any of that
information since the data is minimally processed. As a result we were
seeing malicious driver detection (MDD) events being triggered when the PF
had that functionality enabled.
To address this I have added a bit of new code that will "prime" the XDP
ring by providing one context descriptor that assumes the minimal setup of
an Ethernet frame which is an L2 header length of 14. With just that we can
provide enough information to make the hardware happy so that we don't
trigger MDD events.

Issuing "ip link set up/down" can block TSICR interrupts, what results in
missing PTP Tx timestamp and no PPS pulse generation.
Problem happens when the link is set up with the TSICR interrupts pending.
ICR is cleared before enabling interrupts, while TSICR is not. When all TSICR
interrupts are pending at this moment, time_sync interrupt will never
be generated. TSICR should be cleared as well.
In order to reproduce the issue:
1. Setup linux with IEEE 1588 grandmaster and PPS output enabled
2. Continue setting link up/down with random intervals between commands
3. Wait until PPS is not generated ( only one pulse is generated and PPS
dies), and ptp4l complains constantly about Tx timeout.

There have been multiple reports of crashes that look like
kernel: RIP: 0010:[<ffffffff8110303f>] timecounter_read+0xf/0x50

kernel: [<ffffffff8163184f>] ret_from_fork+0x3f/0x70
These can be traced back to the fact that e1000e_systim_reset() skips the
timecounter_init() call if e1000e_get_base_timinca() returns -EINVAL, which
leads to a null deref in timecounter_read().
Commit 83129b37ef35 ("e1000e: fix systim issues", v4.2-rc1) reworked
e1000e_get_base_timinca() in such a way that it can return -EINVAL for
e1000_pch_spt if the SYSCFI bit is not set in TSYNCRXCTL.
Some experimentation has shown that on I219 (e1000_pch_spt, "MAC: 12")
adapters, the E1000_TSYNCRXCTL_SYSCFI flag is unstable; TSYNCRXCTL reads
sometimes don't have the SYSCFI bit set. Retrying the read shortly after
finds the bit to be set. This was observed at boot (probe) but also link up
and link down.
Moreover, the phc (PTP Hardware Clock) seems to operate normally even after
reads where SYSCFI=0. Therefore, remove this register read and
unconditionally set the clock parameters.

git://git.kernel.org/pub/scm/linux/kernel/git/leon/linux-rdma.git into for-next
Pull verbs counters series from Leon Romanovsky:
====================
Verbs flow counters support
This series comes to allow user space applications to monitor real time
traffic activity and events of the verbs objects it manages, e.g.: ibv_qp,
ibv_wq, ibv_flow.
The API enables generic counters creation and define mapping to
association with a verbs object, the current mlx5 driver is using this API
for flow counters.
With this API, an application can monitor the entire life cycle of object
activity, defined here as a static counters attachment. This API also
allows dynamic counters monitoring of measurement points for a partial
period in the verbs object life cycle.
In addition it presents the implementation of the generic counters
interface.
This will be achieved by extending flow creation by adding a new flow
count specification type which allows the user to associate a previously
created flow counters using the generic verbs counters interface to the
created flow, once associated the user could read statistics by using the
read function of the generic counters interface.
The API includes:
1. create and destroyed API of a new counters objects
2. read the counters values from HW
Note:
Attaching API to allow application to define the measurement points per
objects is a user space only API and this data is passed to kernel when
the counted object (e.g. flow) is created with the counters object.

Commit 1383cb8103bb ("mlx4_core: allocate ICM memory in page size chunks")
brought two regressions caught in our regression suite.
The big one is an additional cost of 256 bytes of overhead per 4096 bytes,
or 6.25 % which is unacceptable since ICM can be pretty large.
This comes from having to allocate one struct mlx4_icm_chunk (256 bytes)
per MLX4_TABLE_CHUNK, which the buggy commit shrank to 4KB
(instead of prior 256KB)
Note that mlx4_alloc_icm() is already able to try high order allocations
and fallback to low-order allocations under high memory pressure.
Most of these allocations happen right after boot time, when we get
plenty of non fragmented memory, there is really no point being so
pessimistic and break huge pages into order-0 ones just for fun.
We only have to tweak gfp_mask a bit, to help falling back faster,
without risking OOM killings.
Second regression is an KASAN fault, that will need further investigations.

Filling in the padding slot in the bpf structure as a bug fix in 'ne'
overlapped with actually using that padding area for something in
'net-next'.

We can bail out immediately also in case of PHY_IGNORE_INTERRUPT because
phy_mac_interupt() informs us once the link is up.
