Subject: instead of passing rx tstamp and rssi to the ieee80211_input function,
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=30d05aace5dfc9e238681bc4d88f40b3eb18547b;p=openbsd

instead of passing rx tstamp and rssi to the ieee80211_input function,
pass a pointer to an ieee80211_rxinfo structure containing those two
fields plus an extra flags field that indicates whether the frame was
decrypted by hardware or not.
required for a future fix.
