Subject: mac80211: NOHZ: local_softirq_pending 08

Hi,

mac80211 (or some other part of the networking stack) triggers this warning
in the NOHZ code:
NOHZ: local_softirq_pending 08

08 seems to be NET_RX_SOFTIRQ.

It happens, because my test driver b43 handles all RX and TX-status callbacks in
process context. I guess some part of the networking stack expects RX to be in
tasklet and/or softirq context.

We also have a report of this warning in wl1251, so it's probably not a b43 problem.
