From c0c56955e7325ba2f910c760111457adc21ef0d4 Mon Sep 17 00:00:00 2001 From: Ron Mercer Date: Wed, 17 Feb 2010 06:41:21 +0000 Subject: [PATCH] qlge: Fix dropping of large non-TCP/UDP frames. This was found with pings that were large enough to span multiple rx buffers. The split frame logic handles this case nicely. Signed-off-by: Ron Mercer Signed-off-by: David S.
