This patchset implements ethtool -X to setup user-defined RSS indirection
table.  The new infrastructure also allows the proper logical ring index
to be used to populate the RSS indirection when queried by ethtool -x.
Prior to these patches, we were incorrectly populating the output of
ethtool -x with internal ring IDs which would make no sense to the user.

The last 2 patches add some cleanups to the VLAN acceleration logic
and check the firmware capabilities before allowing VLAN acceleration
offloads.

v2: Some RSS indirection table changes requested by Jakub Kicinski.

Edwin Peer (2):
  bnxt_en: clean up VLAN feature bit handling
  bnxt_en: allow firmware to disable VLAN offloads

Michael Chan (6):
  bnxt_en: Set up the chip specific RSS table size.
  bnxt_en: Add logical RSS indirection table structure.
  bnxt_en: Add helper function to return the number of RSS contexts.
  bnxt_en: Fill HW RSS table from the RSS logical indirection table.
  bnxt_en: Return correct RSS indirection table entries to ethtool -x.
  bnxt_en: Implement ethtool -X to set indirection table.

Jakub, please review.
