HardenedBSD/sys/net80211/_ieee80211.h
Adrian Chadd 617f8b101e [net80211] RX parameter shuffle in net80211 in preparation for 4x4 NICs and 160MHz channels. 
* Migrate the rx_params stuff out from ieee80211_freebsd.h where it doesn't belong -
  this isn't freebsd specific anymore.

* Don't use a hard-coded number of chains in the ioctl header; now we can shuffle
  MAX_CHAINS around so it can be used in the right spot.

* Extend the signal/noisefloor levels in the mimo stats struct to userland to include
  the signal and noisefloor levels for each 20MHz slice of a 160MHz channel.

* Bump the number of EVM pilots in preparation for 4x4 and 160MHz channels.

Tested:

* ath(4), STA mode
* iwn(4), STA mode
* local ath10k port, STA mode

TODO:

* 11ax chips will come with 5GHz 8x8 hardware for lots of MU-MIMO - I'll re-bump it
  at that point.

Note:

* This breaks the driver and ifconfig ABI; please recompile  the kernel,
  ifconfig and wpa_supplicant/hostapd.
