[PATCH iwl-net 0/4] ice: fixes for pause reporting, autoneg, RDMA and EIPE

[Aleksandr Loktionov <aleksandr.loktionov@intel.com>]

This is v2 of the ice fixes patchset for iwl-net.

v2 changes:
 - Dropped patch "ice: fix 'adjust' timer programming for E830 devices"
   as it has already been applied to the iwl-net tree.

This series fixes four issues in the Intel ice driver:

- Asymmetric Pause capability was missing from the ethtool-reported
  supported link modes, causing ethtool to always show Pause as
  unsupported even when the hardware supports asymmetric flow control.

- Autoneg disable was only attempted when AN had already completed,
  ignoring the case where the link partner does not advertise AN ability
  at all (AN37).  Both conditions should allow the user to disable
  autoneg.

- RDMA was incorrectly disabled on E830 devices with 4 or more ports
  because the generic port-limited-capabilities path capped maxtc=4 and
  then cleared the RDMA capability bit.  E830 does not have that
  limitation and must be skipped.

- On E830, Ethernet Inline IPsec Engine (EIPE) decryption errors trigger
  a checksum-error path that returned early without reporting the error
  to the OS.  The packet must be forwarded to the stack with the
  checksum error flag set so the OS can handle it correctly.
