octeontx2-pf: mcs: Match macsec ethertype along with DMAC

Browse source

[ Upstream commit 57d00d4364 ]

On CN10KB silicon a single hardware macsec block is
present and offloads macsec operations for all the
ethernet LMACs. TCAM match with macsec ethertype 0x88e5
alone at RX side is not sufficient to distinguish all the
macsec interfaces created on top of netdevs. Hence append
the DMAC of the macsec interface too. Otherwise the first
created macsec interface only receives all the macsec traffic.
