*	mac80211: airtime: Fix an off by one in ieee80211_calc_rx_airtime()	Dan Carpenter	2019-12-13	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \|	This code was copied from mt76 and inherited an off by one bug from there. The > should be >= so that we don't read one element beyond the end of the array.

*	mac80211: Import airtime calculation code from mt76	Toke Høiland-Jørgensen	2019-11-22	1	-0/+597
	Felix recently added code to calculate airtime of packets to the mt76 driver. Import this into mac80211 so we can use it for airtime queue limit calculations. The airtime.c file is copied verbatim from the mt76 driver, and adjusted to be usable in mac80211. This involves: - Switching to mac80211 data structures. - Adding support for 160 MHz channels and HE mode. - Moving the symbol and duration calculations around a bit to avoid rounding with the higher rates and longer symbol times used for HE rates. The per-rate TX rate calculation is also split out to its own function so it can be used directly for the AQL calculations later.
