The old WDS 4-addr frame support is very limited, e.g.
* no encryption is possible on such links
* it cannot support rate/HT/VHT negotiation
* management APIs are very restricted
These make the WDS legacy mode useless in practice.
All of these are resolved by the 4-addr AP/client support,
so there's also no reason to improve WDS in the future.
Therefore, add a Kconfig option to disable legacy WDS.
This gives people an "emergency valve" while they migrate
to the better-supported 4-addr AP/client option; we plan
to remove it (and the associated cfg80211/mac80211 code,
which is the ultimate goal) in the future.

This patch fixes a crash that happens because b43's
debugfs code expects file->f_op to be a pointer to
its own b43_debugfs_fops struct. This is no longer
the case since commit 9fd4dcece4
("debugfs: prevent access to possibly dead file_operations at file open")

gcc-6 reports the following error with -Werror=unused-const-variable.

Per Michael Büsch: "All a-phy code is usused", so remove it all,
and move the remaining Type-G initialization code into phy_g.c.

Only hardcode the LED behavior if the SROM doesn't provide any for all
LEDs of the card. This avoids instantiating LED triggers for unconnected
LEDs, while (hopefully) keeping things working for old cards with a
blank SROM.

Check the current PHY operating mode (gmode) to see if we should
fall back from 6MB OFDM to 11MB CCK. For 5GHz operation this isn't
allowed.
Note, the fallback lookup is only done for RTS rates; normal fallback
rates are done via mac80211 and aren't affected by this change.

This enum is already perfectly aliased to enum nl80211_band, and
the only reason for it is that we get IEEE80211_NUM_BANDS out of
it. There's no really good reason to not declare the number of
bands in nl80211 though, so do that and remove the cfg80211 one.

The memory allocated by kzalloc in b43_bus_dev_ssb_init and
b43_bus_dev_bcma_init is not freed.
This patch fixes the bug by adding kfree in b43_ssb_remove,
b43_bcma_remove and error handling code of b43_bcma_probe.
Thanks Michael for his suggestion.

Calling synchronize_irq() right before free_irq() is quite useless. On one
hand the IRQ can easily fire again before free_irq() is entered, on the
other hand free_irq() itself calls synchronize_irq() internally (in a race
condition free way), before any state associated with the IRQ is freed.
Patch was generated using the following semantic patch:
// <smpl>

expression irq;

-synchronize_irq(irq);
free_irq(irq, ...);

PMU (Power Management Unit) seems to be a separated piece of hardware,
just accessed using ChipCommon core registers. In recent Broadcom
chipsets PMU is not bounded to CC but available as separated core.
To make code cleaner & easier to review (for a correct R/W access) use
clearer names.
