In virtio_net.c,
#ifdef COMPAT_csum_offset
if (skb->ip_summed == CHECKSUM_HW) {
#else
if (skb->ip_summed == CHECKSUM_PARTIAL) {
It seems that CHECKSUM_HW is not declared.
In skbuff.h, only the macros below are defined.
/* Don't change this without changing skb_csum_unnecessary! */
#define CHECKSUM_NONE 0
#define CHECKSUM_UNNECESSARY 1
#define CHECKSUM_COMPLETE 2
#define CHECKSUM_PARTIAL 3
Cheers,
