[net-next,v2,0/3] DMAC based packet filtering

Message

Hariprasad Kelam June 29, 2021, 12:20 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 commands.

Change-log:
v2 -
   - fixed indentation issues.
