From c8cd0989bd151fda87bbf10887b3df18021284bc Mon Sep 17 00:00:00 2001 From: Tom Herbert Date: Mon, 14 Dec 2015 11:19:44 -0800 Subject: net: Eliminate NETIF_F_GEN_CSUM and NETIF_F_V[46]_CSUM These netif flags are unnecessary convolutions. It is more straightforward to just use NETIF_F_HW_CSUM, NETIF_F_IP_CSUM, and NETIF_F_IPV6_CSUM directly.
