In br_dev_queue_push_xmit, why is the check to drop mtu oversized
packets not checking for enough room for the impending ETH_HLEN size
skb_push? In some code currently under development, we are seeing
skb_under_panic being called from the "skb_push(skb, ETH_HLEN)" in that
code. It seems to me it would be better to drop those skbs than panic.
Attached is a patch to do this.
Thanks,
Jon
