From af33c1adae1e095e90d14fe35501256ebb07aabf Mon Sep 17 00:00:00 2001 From: Tom Herbert Date: Tue, 20 Jan 2015 11:23:05 -0800 Subject: vxlan: Eliminate dependency on UDP socket in transmit path In the vxlan transmit path there is no need to reference the socket for a tunnel which is needed for the receive side. We do, however, need the vxlan_dev flags. This patch eliminate references to the socket in the transmit path, and changes VXLAN_F_UNSHAREABLE to be VXLAN_F_RCV_FLAGS. This mask is used to store the flags applicable to receive (GBP, CSUM6_RX, and REMCSUM_RX) in the vxlan_sock flags. Signed-off-by: Tom Herbert Signed-off-by: David S.
