[NET]: Don't send ICMP_FRAG_NEEDED for GSO packets
Commit 9af3912ec9e30509b76cb376abb65a4d8af27df3 ("[NET] Move DF check to ip_forward") added a new check to send ICMP fragmentation needed for large packets. Unlike the check in ip_finish_output(), it doesn't check for GSO. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: David S. Miller <davem@davemloft.net>
