From 8648b3053bff39a7ee4c711d74268079c928a657 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Sat, 17 Jun 2006 22:06:05 -0700 Subject: [NET]: Add NETIF_F_GEN_CSUM and NETIF_F_ALL_CSUM The current stack treats NETIF_F_HW_CSUM and NETIF_F_NO_CSUM identically so we test for them in quite a few places. For the sake of brevity, I'm adding the macro NETIF_F_GEN_CSUM for these two. We also test the disjunct of NETIF_F_IP_CSUM and the other two in various places, for that purpose I've added NETIF_F_ALL_CSUM. Signed-off-by: Herbert Xu Signed-off-by: David S.
