flow_dissector: Move skb related functions to skbuff.h
Move the flow dissector functions that are specific to skbuffs into skbuff.h out of flow_dissector.h. This makes flow_dissector.h have no dependencies on skbuff.h. Signed-off-by: Tom Herbert <tom@herbertland.com> Signed-off-by: David S. Miller <davem@davemloft.net>
