Hello! > ip_output() ignores dev->hard_header_len
ip_output() worries about the space, which it needs. If some place needs more, it is its problem to check. To the moment where it is used, hard_header_len can even change. It can be applied, but it does not change the fact, that those placed which fail now must check the condition as well. > A similar problem may be present in psched_mtu(). Nothing similar. The result psched_mtu() is compared with skb->len, how it is seen by qdiscs. If hard_header is NULL, it sees skbs without header.
