Hi=20

why does virtio not support IPv4 CKSUM? But support TCP/UDP cksum.

If not support ipv4 cksum, when I use GRO, the ip cksum of the packets tran=
smitted to ip layer will be incorrect.
I have to calculate ip cksum before packet was transmiited to ip layer.
So why does virtio not support ipv4 cksum ?=20
