rocker: add offload_fwd_mark support
If device flags ingress packet as "fwd offload", mark the
skb->offlaod_fwd_mark using the ingress port's dev->offlaod_fwd_mark. This
will be the hint to the kernel that this packet has already been forwarded
by device to egress ports matching skb->offlaod_fwd_mark.
For rocker, derive port dev->offlaod_fwd_mark based on device switch ID and
port ifindex. If port is bridged, use the bridge ifindex rather than the
port ifindex.
