The rt2800pci driver supports the built-in wireless
MAC of the Ralink RT3x5x SoCs. However building the
driver for these SoCs leads to the following error:
LD init/built-in.o

make[5]: *** [vmlinux] Error 1
The missing functions are provided by the rt2x00pci
module. This module is only selected by the rt2800pci
driver if PCI support is enabled in the kernel, because
some parts of the rt2x00pci code depends on PCI support.
PCI support is not available on the RT3x5x SoCs because
those have no PCI host controller at all.
Move the non PCI specific code from rt2x00pci into a
separate module. This makes it possible to use that
code even if PCI support is disabled. The affected
functions are used by all of the rt2x00 PCI drivers
so select the new module for those drivers.

Alex Romosan reported that since the mac80211 changes in
"mac80211: start auth/assoc timeout on frame status" and
the subsequent fixes in "mac80211: fix auth/assoc timeout
handling" (commits 1672c0e319 and 89afe614c0) there's
sometimes an issue connecting to a 5 GHz network with the
iwlwifi DVM driver.
The reason appears to be that since these commits any bad
TX status makes mac80211 immediately try again, causing
all of the authentication attempts to be quickly rejected
by the firmware as it hasn't heard a beacon yet. Before,
it would wait for the timeout regardless of status.
To fix this, invoke the passive-no-RX workaround when not
associated yet as well. This will cause the first frame
to get lost, but then the driver will stop the queues and
the second attempt will only be transmitted after hearing
a beacon, thus delaying it appropriately to not make the
firmware reject it again.

Marco Fonseca reported a issue with his carl9170 device:
"I'm seeing a problem with the carl driver. If I change channels
repeatedly on the 2.4ghz band, monitoring (e.g. tcpdump) will
eventually halt. I've seen this on various versions of the carl
driver/firmware (both from 1.9.4 to 1.9.7)"
<http://marc.info/?l=linux-wireless&m=136381302428113>
The culprit was identified as "fast channel change feature" which
according to Adrian Chadd is: "... notoriously unreliable and
really only fully debugged on some very later chips."
<http://marc.info/?l=linux-wireless&m=136416984531380>
Therefore, this patch removes the fast channel change feature.
The phy will now always have to go through a cold reset when

Fix settings not being applied when the device is idle and the firmware
gets reloaded (because of changing from STA to AP mode). This caused
the device using the wrong channel (and likely band), e.g. a 5 GHz only
card still defaulted to channel 6 in the 2.4 GHz band when left
unconfigured.
This issue was always present, but only made visible with "mwl8k: Do not
call mwl8k_cmd_set_rf_channel unconditionally" (0f4316b9), since before
that the channel was (re-)configured at the next _config call even when
it did not change from the mac80211 perspective.
