Thank you for the wiki! :)

But I am having a problem with athsurvey which is just reporting:

         min                   avg                   max
  tx%  rx%  bc%  ec%    tx%  rx%  bc%  ec%    tx%  rx%  bc%  ec%
(100.0 100.0 100.0 100.0) ( 0.0  0.0  0.0  0.0) ( 0.0  0.0  0.0  0.0)
(100.0 100.0 100.0 100.0) ( 0.0  0.0  0.0  0.0) ( 0.0  0.0  0.0  0.0)

athdebug is returning with:
athdebug: sysctl-get(dev.ath.0.debug): Cannot allocate memory

This is in my kernel config:
...
# Atheros wireless NICs
device		ath             # Atheros interface support
device		ath_pci		# Atheros PCI/Cardbus bus
options 	ATH_DEBUG
options		ATH_DIAGAPI
options		ATH_ENABLE_11N
options		AH_DEBUG
options		AH_DEBUG_ALQ
options		ALQ
device		ath_hal
option		AH_SUPPORT_AR5416
device		ath_rate_sample
option		AH_RXCFG_SDMAMW_4BYTES
option		AH_AR5416_INTERRUPT_MITIGATION
# There's no DFS radar detection support yet so this won't actually
# detect radars.  It however does enable the rest of the channel change
# machinery so DFS can be debugged.
option		ATH_ENABLE_DFS


pciconf -lbvc gives:
ath0_at_pci0:0:17:0:       class=0x020000 card=0x30020777 chip=0x001b168c

    cap 01[44] = powerspec 2  supports D0 D3  current D0


I am running head_at_235822
