octeontx2-af: Add packet path between representor and VF
Current HW, do not support in-built switch which will forward pkts
between representee and representor. When representor is put under
a bridge and pkts needs to be sent to representee, then pkts from
representor are sent on a HW internal loopback channel, which again
will be punted to ingress pkt parser. Now the rules that this patch
installs are the MCAM filters/rules which will match against these
pkts and forward them to representee.
The rules that this patch installs are for basic
representor <=> representee path similar to Tun/TAP between VM and
Host.
