From 7c62e83beb1446d690ed921beddb0dcf34c9baa9 Mon Sep 17 00:00:00 2001 From: Michael Chan Date: Mon, 14 Jul 2008 22:39:03 -0700 Subject: [PATCH] bnx2: Allow flexible VLAN tag settings. Negotiate with boot code and ASF firmware to see if it can support keeping VLAN tags in the RX packets. If supported by firmware, the VLAN tag will be kept in the RX packet unless VLAN acceleration is registered. Signed-off-by: Michael Chan Signed-off-by: David S.
