I wonder if the test on line 302 ish in core.c should be <=. The head
delta is 0, which actually means its doesn't need to be increased in
size.
if (skb_headroom(skb) < drvr->hdrlen || skb_header_cloned(skb)) {
<<<< should be <=
head_delta = max_t(int, drvr->hdrlen - skb_headroom(skb), 0);
Don't think this could be the cause of the problem though.
