From 8400dd029e764e30361a51a7ae35900ae0032b43 Mon Sep 17 00:00:00 2001 From: Neil Horman Date: Wed, 17 Sep 2014 09:04:45 -0400 Subject: [PATCH] 3c59x: Fix bad offset spec in skb_frag_dma_map Recently aded the use of skb_frag_dma_map to 3c59x, but didn't realize it automatically included the frag_offset internally, as well as provided an option to specify an extra offset in the parameter list. We need to specify an offset of 0 in the parameter list to avoid skb corruption that results in lost connections. Signed-off-by: Neil Horman CC: Linux Kernel list CC: "David S.
