[PATCH iwl-net v3 0/3] ice: fixes for pause reporting, autoneg and RDMA

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

This is v3 of the ice fixes patchset for iwl-net.

v3 changes:
 - Patch "ice: support RDMA on 4+-port E830 devices": gate the
   "RDMA functionality is not available" dev_info() on the same
   condition that actually disables caps->rdma, instead of printing
   it unconditionally whenever num_funcs > 4. This addresses Simon
   Horman's review comment that E830 would otherwise log a spurious
   warning even though RDMA stays enabled on that hardware.
 - Patches "ice: fix asymmetric pause negotiation reporting in
   ethtool" and "ice: fix autoneg disable when link partner doesn't
   support AN" are unchanged since v2 (Reviewed-by: Simon Horman
   carried forward).

This series fixes three 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.
