Non-linear skbs are truncated to their linear part with mmaped IO.

Are you using TSO on the outgoing device? If so please try to log the

Good catch! I turned off TSO and things are working fine again.
Is this a known problem, should it

Ack.
I remember this trick. The idea was that I needed only TCP header in any

Hi people,
I like to use memory mapped pcap (PACKET_MMAP) since off the shelf, linux is
a tad prone to drop packets while capturing these days. It used to be lots
better at it, but right now memory mapped pcap is the only way to get things
working a bit. I've noticed this on many machines.
