27b4eb26cd b43: N-PHY: rev3+: add static tables
This finally makes TX on OFDM rates possible on my dev with PHY rev 4.
We still have lower performance than wl, but at least speeds around 15M
become possible.

3311abbbbf b43: fill PHY ctl word1 in TX header for N-PHY
This patch fixes tramissing on OFDM rates for PHYs 1 and 2. There is
still something wrong with PHYs 3+. Tests has shown decreasing of
performance on CCK rates by 1-2%, we have to live with that.
Additionaly this noticeably reduces amount of PHY errors. They were
mostly produced by auto-switching to higher rate for better
performanced, which resulted in no transmit at all and PHY errors.

7bb4568372 mac80211: make tx() operation return void
The return value of the tx operation is commonly
misused by drivers, leading to errors. All drivers
will drop frames if they fail to TX the frame, and
they must also properly manage the queues (if they
didn't, mac80211 would already warn).

Removing the ability for drivers to return a BUSY
value also allows significant cleanups of the TX
TX handling code in mac80211.

Note that this also fixes a bug in ath9k_htc, the
old "return -1" there was wrong.

6ebacbb79d mac80211: rename RX_FLAG_TSFT
The flag isn't very descriptive -- the intention
is that the driver provides a TSF timestamp at
the beginning of the MPDU -- make that clearer
by renaming the flag to RX_FLAG_MACTIME_MPDU.

42ab135fe7 b43: rename TMS defines, drop useless condition from core reset
As discussed we do not know band width at core reset time and it is not a good
idea to reset whole just to change band. So just set unconditionally 20 MHz
band width as default during core reset.

As for defines PHY clock changed to band width in specs and it makes much more
sens to call defines by band width which is self-explainable. Updated specs do
not mention 0 value, but comparing to old ones you can notice lineral relation
between PHY clock speed and band width. So it makes sense for 0x0 value to be
10 MHz band width.

69a3229edc b43: N-PHY: fix values for PHY regs in channel tables of 2055 radio
Additional comment by Larry Finger <Larry.Finger@lwfinger.net>:

This change deserves a bit more explanation. You might include something like
"These tables came from reverse engineering the 5.10.56.46 version of the
Broadcom driver. Trace comparisons between b43 and the current Broadcom driver
(5.10.120.0) show byte reversals for the PHY register writes."
