Should be fixed by: commit 8400dd029e764e30361a51a7ae35900ae0032b43 Author: Neil Horman <[email protected]> Date: Wed Sep 17 09:04:45 2014 -0400 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.
