From 9227a46bfbac0516fb7428715a095e1bc59b872a Mon Sep 17 00:00:00 2001 From: Jussi Kivilinna Date: Mon, 7 Jun 2010 00:56:27 -0700 Subject: asix: check packet size against mtu+ETH_HLEN instead of ETH_FRAME_LEN Driver checks received packet is too large in asix_rx_fixup() and fails if it is. Problem is that MTU might be set larger than 1500 and asix fails to work correctly with VLAN tagged packets. The check should be 'dev->net->mtu + ETH_HLEN' instead. Tested with AX88772.
