Merge branch 'bnxt_en-ntuple-and-rss-updates'

Michael Chan says:

====================
bnxt_en: Ntuple and RSS updates

This patch series adds more ntuple and RSS features following recent
patches to add support for user configured ntuple filters.  Additional
features include L2 ether filters, partial tuple masks, IP filters
besides TCP/UDP, drop action, saving and re-applying user filters
after driver reset, user configured RSS key, and RSS for IPSEC.
