      efx_default_channel_want_txqs() is only used in efx.c, while
 efx_ptp_want_txqs() and efx_ptp_channel_type (a struct) are only used
 in ptp.c.  In all cases these symbols should be static.

40GbE Intel Wired LAN Driver Updates 2018-01-26

This series contains updates to i40e and i40evf.

Michal updates the driver to pass critical errors from the firmware to
the caller.

Patryk fixes an issue of creating multiple identical filters with the
same location, by simply moving the functions so that we remove the
existing filter and then add the new filter.

Paweł adds back in the ability to turn off offloads when VLAN is set for
the VF driver.  Fixed an issue where the number of TC queue pairs was
exceeding MSI-X vectors count, causing messages about invalid TC mapping
and wrong selected Tx queue.

Alex cleans up the i40e/i40evf_set_itr_per_queue() by dropping all the
unneeded pointer chases.  Puts to use the reg_idx value, which was going
unused, so that we can avoid having to compute the vector every time
throughout the driver.

Upasana enable the driver to display LLDP information on the vSphere Web
Client by exposing DCB parameters.

Alice converts our flags from 32 to 64 bit size, since we have added
more flags.

Dave implements a private ethtool flag to disable the processing of LLDP
packets by the firmware, so that the firmware will not consume LLDPDU
and cause them to be sent up the stack.

Alan adds a mechanism for detecting/storing the flag for processing of
LLDP packets by the firmware, so that its current state is persistent
across reboots/reloads of the driver.

Avinash fixes kdump with i40e due to resource constraints.  We were
enabling VMDq and iWARP when we just have a single CPU, which was
starving kdump for the lack of IRQs.

Jake adds support to program the fragmented IPv4 input set PCTYPE.
Fixed the reported masks to properly report that the entire field is
masked, since we had accidentally swapped the mask values for the IPv4
addresses with the L4 port numbers.

pull-request: bpf-next 2018-01-26

The following pull-request contains BPF updates for your *net-next* tree.

The main changes are:

1) A number of extensions to tcp-bpf, from Lawrence.
    - direct R or R/W access to many tcp_sock fields via bpf_sock_ops
    - passing up to 3 arguments to bpf_sock_ops functions
    - tcp_sock field bpf_sock_ops_cb_flags for controlling callbacks
    - optionally calling bpf_sock_ops program when RTO fires
    - optionally calling bpf_sock_ops program when packet is retransmitted
    - optionally calling bpf_sock_ops program when TCP state changes
    - access to tclass and sk_txhash
    - new selftest

2) div/mod exception handling, from Daniel.
    One of the ugly leftovers from the early eBPF days is that div/mod
    operations based on registers have a hard-coded src_reg == 0 test
    in the interpreter as well as in JIT code generators that would
    return from the BPF program with exit code 0. This was basically
    adopted from cBPF interpreter for historical reasons.
    There are multiple reasons why this is very suboptimal and prone
    to bugs. To name one: the return code mapping for such abnormal
    program exit of 0 does not always match with a suitable program
    type's exit code mapping. For example, '0' in tc means action 'ok'
    where the packet gets passed further up the stack, which is just
    undesirable for such cases (e.g. when implementing policy) and
    also does not match with other program types.
    After considering _four_ different ways to address the problem,
    we adapt the same behavior as on some major archs like ARMv8:
    X div 0 results in 0, and X mod 0 results in X. aarch64 and
    aarch32 ISA do not generate any traps or otherwise aborts
    of program execution for unsigned divides.
    Given the options, it seems the most suitable from
    all of them, also since major archs have similar schemes in
    place. Given this is all in the realm of undefined behavior,
    we still have the option to adapt if deemed necessary.

3) sockmap sample refactoring, from John.

4) lpm map get_next_key fixes, from Yonghong.

5) test cleanups, from Alexei and Prashant.

====================
10GbE Intel Wired LAN Driver Updates 2018-01-26

This series contains updates to ixgbe and ixgbevf.

Emil updates ixgbevf to match ixgbe functionality, starting with the
consolidating of functions that represent logical steps in the receive
process so we can later update them more easily.  Updated ixgbevf to
only synchronize the length of the frame, which will typically be the
MTU or smaller.  Updated the VF driver to use the length of the packet
instead of the DD status bit to determine if a new descriptor is ready
to be processed, which saves on reads and we can save time on
initialization.  Added support for DMA_ATTR_SKIP_CPU_SYNC/WEAK_ORDERING
to help improve performance on some platforms.  Updated the VF driver to
do bulk updates of the page reference count instead of just incrementing
it by one reference at a time.  Updated the VF driver to only go through
the region of the receive ring that was designated to be cleaned up,
rather than process the entire ring.

Colin Ian King adds the use of ARRAY_SIZE() on various arrays.

Miroslav Lichvar fixes an issue where ethtool was reporting timestamping
filters unsupported for X550, which is incorrect.

Paul adds support for reporting 5G link speed for some devices.

Dan Carpenter fixes a typo where && was used when it should have been
||.
