Subject: mac80211: Print unknown packet type in tasklet_handler
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5e3f308997f53d00e8cbebdb89d4f6e347aa963a;p=linux-beck.git

mac80211: Print unknown packet type in tasklet_handler

In stress testing p54usb, the WARN_ON() in ieee80211_tasklet_handler() was
triggered; however, there is no logging of the received value for packet
type. Adding that feature will improve the warning.
