From 6d90e8f45697c633f522269368297d7416fd8783 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Tue, 15 Feb 2011 12:18:09 -0800 Subject: [PATCH] isdn: hisax: Use l2headersize() instead of dup (and buggy) func. There was a bug in my commit c978e7bb77dfd2cd3d1f547fa4e395cfe47f02b2 ("hisax: Fix unchecked alloc_skb() return.") One of the l2->flag checks is wrong. Even worse it turns out I'm duplicating an existing function, so use that instead. Reported-by: Milton Miller Signed-off-by: David S.
