[PATCH 0/7] b43: N-PHY fixes, check dependency before applying

[Rafał Miłecki]

Some N-PHY fixes coming from wl observations and specs changes.

Please note this patchset depends on following patches:
[PATCH 1/2] ssb: extract FEM info from SPROM
[PATCH 2/2] bcma: extract FEM info from SPROM
send 3 days ago.

Rafał Miłecki (7):
  b43: N-PHY: random trivial fixes for typos, missing writes
  b43: N-PHY: update some init values
  b43: N-PHY: workaround BCM43224 hw bug in writing table id 9
  b43: N-PHY: add table for antenna software control
  b43: N-PHY: determine various PHY params
  b43: N-PHY: finish 2.4GHz 0x2056 radio setup
  b43: N-PHY: implement spurious tone avoidance

There was off-by-one in tx2rx_events and tx2rx_delays arrays. Use
ARRAY_SIZE to avoid such mistakes.

Also, I've never meant to write numbers in octal system :| I really
forgot that leading 0 means octal :/

This set of patches improved the performance of my BCM43224.

netperf TCP_MAERTS (RX)  15.0 => 24.5 Mbps
netperf TCP_STREAM (TX)   6.0 => 13.1 Mbps

I have mac80211 debug on, and I see a lot of

wlan13: detected beacon loss from AP - sending probe request

These occur at 1 second intervals. This particular AP does not have a setting 
for the beacon interval, but I think it is at 100 ms.

Re: [PATCH 0/7] b43: N-PHY fixes, check dependency before applying

[Larry Finger]

Rafał,

I checked the network traffic on the 43224 using kismet. The beacons are clearly 
seen in the capture; however, they appear not to get back to mac80211. I'll look 
for the reason.

It's not brain dead =)

It's set in all paths, but there is no way to guarantee that one of
the paths will be taken - they all have conditions.

Something like the following might be better:
