I've thrown this on my apu2 and done some tests with my ipad, android
phones and some openbsd laptops. Streamed 1080p from youtube works on
one device but when I try with 2x it starts to buffer a bit.
Tested on 2.4Ghz:
athn0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
index 4 priority 4 llprio 3
groups: wlan
media: IEEE802.11 autoselect hostap

ieee80211: nwid mynwid chan 7 bssid xxxxxxxxxxxxxxxxx wpakey
0x5324766a441a60e61749083489bcea5df6e73deb1ddbcbe6b1054270787bb4fe wpaprotos
wpa2 wpaakms psk wpaciphers ccmp wpagroupcipher ccmp
inet 192.168.1.1 netmask 0xffffff00 broadcast 192.168.1.255
OpenBSD shows:
media: IEEE802.11 autoselect (HT-MCS5 mode 11n)
I'm seeing some decent throughput on DL:

With 5Ghz I'm only able to test on my android/ipad, and I'm able to stream a
couple 1080p videos at the same time without any issues:

I'll apply your other diffs and test more.
Cheers!
