From 4487e64de63b8e42efe5a5543871c42c5a5859d9 Mon Sep 17 00:00:00 2001 From: Andy Cress Date: Thu, 26 Jul 2012 06:01:17 +0000 Subject: [PATCH] pch_gbe: vlan skb len fix pch_gbe_xmit_frame skb->len verification was incorrect in vlan case causing bogus transfer length errors. One correction could be: offset = skb->protocol == htons(ETH_P_8021Q) ? 0 : 4; if (unlikely(skb->len > (adapter->hw.mac.max_frame_size - offset))) However, this verification is not necessary, so remove it.
