sfc: Add channel specific receive_skb handler and post_remove callback

Browse Source 
Allows an extra channel to override the standard receive_skb handler
and also for extra non generic operations to be performed on remove.

Also set default rx strategy so only skbs can be delivered to the
PTP receive function.
