From e4f7dbb17e797d922d72567f37de3735722034ba Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Thu, 21 Feb 2013 03:08:50 +0000 Subject: [PATCH] igb: Drop BUILD_BUG_ON check from igb_build_rx_buffer On s390 the igb driver was throwing a build error due to the fact that a frame built using build_skb would be larger than 2K. Since this is not likely to change at any point in the future we are better off just dropping the check since we already had a check in igb_set_rx_buffer_len that will just disable the usage of build_skb anyway.
