From: greearb@...delatech.com Date: Wed, 1 Jun 2011 09:49:10 -0700 > From: Ben Greear <greearb@...delatech.com> > > Currently, user-space cannot determine if a 0 tcp_vlan_tci > means there is no VLAN tag or the VLAN ID was zero. > > Add flag to make this explicit. User-space can check for > TP_STATUS_VLAN_VALID || tp_vlan_tci > 0, which will be backwards > compatible. Older could would have just checked for tp_vlan_tci, > so it will work no worse than before. > > Signed-off-by: Ben Greear <greearb@...delatech.com> Applied. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
