From bdeab991918663aed38757904219e8398214334c Mon Sep 17 00:00:00 2001 From: Tom Herbert Date: Sun, 14 Aug 2011 19:45:55 +0000 Subject: rps: Add flag to skb to indicate rxhash is based on L4 tuple The l4_rxhash flag was added to the skb structure to indicate that the rxhash value was computed over the 4 tuple for the packet which includes the port information in the encapsulated transport packet. This is used by the stack to preserve the rxhash value in __skb_rx_tunnel. Signed-off-by: Tom Herbert Signed-off-by: David S.
