Hi,

I get a hard crash of my system when experimenting with netmap, pkt-gen and
iwlwifi (Intel WiFi driver).

Linux 3.13, latest netmap from git.

insmod netmap_lin.ko
pkt-gen -f rx -i wlp1s0
... kaboom (corrupted display, hard crash, no oops even)

pkt-gen on a wired interface works fine.

I tried to debug this myself, but couldn't find anything.

Perhaps someone else with Intel WiFi could attempt the same? -Huw
