From 4c3eb3ca13966508bcb64f39dcdef48be22f1731 Mon Sep 17 00:00:00 2001 From: Eli Cohen Date: Thu, 26 Aug 2010 17:19:22 +0300 Subject: IB/mlx4: Add VLAN support for IBoE This patch allows IBoE traffic to be encapsulated in 802.1Q tagged VLAN frames. The VLAN tag is encoded in the GID and derived from it by a simple computation. The netdev notifier callback is modified to catch VLAN device addition/removal and the port's GID table is updated to reflect the change, so that for each netdevice there is an entry in the GID table. When the port's GID table is exhausted, GID entries will not be added. Only children of the main interfaces can add to the GID table; if a VLAN interface is added on another VLAN interface (e.g. "vconfig add eth2.6 8"), then that interfaces will not add an entry to the GID table.
