From a334872224a67b614dc888460377862621f3dac7 Mon Sep 17 00:00:00 2001 From: Barak Witkowski Date: Mon, 23 Apr 2012 03:04:46 +0000 Subject: [PATCH] bnx2x: add afex support Following patch adds afex multifunction support to the driver (afex multifunction is based on vntag header) and updates FW version used to 7.2.51. Support includes the following: 1. Configure vif parameters in firmware (default vlan, vif id, default priority, allowed priorities) according to values received from NIC. 2. Configure FW to strip/add default vlan according to afex vlan mode. 3. Notify link up to OS only after vif is fully initialized. 4. Support vif list set/get requests and configure FW accordingly. 5. Supply afex statistics upon request from NIC. 6. Special handling to L2 interface in case of FCoE vif. Signed-off-by: Barak Witkowski Signed-off-by: Eilon Greenstein Signed-off-by: David S.
