[RFC] mac80211: Print unknown packet type

[Larry Finger <Larry.Finger@lwfinger.net>]

Johannes,

I'm trying to find a problem with p54usb that causes it to go belly-up under
stress testing. In one of my runs, I hit the WARN_ON in
ieee80211_tasklet_handler(). Unfortunately, I got no indication of what was in
skb->pkt_type, just that it was not one of the expected types.

Do you think that adding the printk below would be worthwhile?

Thanks,

Larry
