[net-next,0/3] DMAC based packet filtering

Message

Hariprasad Kelam June 28, 2021, 5:06 p.m. UTC

Each MAC block supports 32 DMAC filters which can be
configured to accept or drop packets based on address match
This patch series adds mbox handlers and extends ntuple filter
callbacks to accomdate DMAC filters such that user can install
DMAC based filters on interface from ethtool.

Patch1 adds necessary mbox handlers such that mbox consumers
like PF netdev can add/delete/update DMAC filters and Patch2 adds
debugfs support to dump current list of installed filters.
Patch3 adds support to call mbox handlers upon receiving DMAC
filters from ethtool ntuple commans.
