Module Name:    src
Committed By:   dyoung

Modified Files:
        src/sys/dev/ic: rtw.c
        src/sys/net80211: ieee80211_output.c ieee80211_proto.h

Log Message:
Fix a bug in ieee80211_compute_duration: the 802.11 Duration field
in an 802.11 unicast data packet is equal to the duration of the
SIFS and Acknowledgement.  That is, the amount of time reserved
*after* the packet has finished transmitting.

Change the arguments to ieee80211_compute_duration: pass the entire
packet length, not just the payload length.  Add a 'debug' argument
to ieee80211_compute_duration and its helper subroutine,
ieee80211_compute_duration1.

If debug != 0, ieee80211_compute_duration printfs its arguments
and several local variables.

In rtw(4), load the 802.11 Duration field with the result from
ieee80211_compute_duration.
