This patch removed the 'raw gso min size - 1' test which
always fails now:
./in_netns.sh ./psock_snd -v -c -g -l "${mss}"
raw gso min size - 1 (expected to fail)
tx: 1524
rx: 1472
OK
After commit 7c6d2ecbda
("net: be more gentle about silly
gso requests coming from user"), we relaxed the min gso_size
check in virtio_net_hdr_to_skb().
So when a packet which is smaller then the gso_size,
GSO for this packet will not be set, the packet will be
send/recv successfully.
