9e4982f6a5 ath5k: fix hardware queue index assignment
Like with ath9k, ath5k queues also need to be ordered by priority.
queue_info->tqi_subtype already contains the correct index, so use it
instead of relying on the order of ath5k_hw_setup_tx_queue calls.

ad8fdccf9c ath9k_hw: fix hardware queue allocation
The driver passes the desired hardware queue index for a WMM data queue
in qinfo->tqi_subtype. This was ignored in ath9k_hw_setuptxqueue, which
instead relied on the order in which the function is called.

dc50a52a36 Revert "rt2x00: Endless loop on hub port power down"
This reverts commit 2ad69ac597. It
causes wireless device disappear when we get -EPROTO error form USB
request. I encounter such situation occasionally when resume form
suspend with RT3070 adapter:

[  289.619985] ieee80211 phy0: rt2x00usb_vendor_request: Error - Vendor Request 0x06 failed for offset 0x0404 with error -71
[  289.639368] ieee80211 phy0: rt2800_wait_bbp_ready: Error - BBP register access failed, aborting
[  289.639374] ieee80211 phy0: rt2800usb_set_device_state: Error - Device failed to enter state 4 (-5)

Without the patch, except printing error, device works just fine after
resume.

Currently after timeouts and REGISTER_BUSY_COUNT tuning, we should
not have any "endless loop", though we can wait quite long when driver
is trying to communicate with the device through non functioning USB
connection. Generally the problem that commit 2ad69ac597 solves
is kinda artificial.

87dd2d76a9 rt2800: calculate tx power temperature compensation on selected chips
Currently implemented temperature compensation is only valid on some of
supported chips. Other chips do not need temperature compensation or
need different way to do this (not yet implemented in the rt2800
driver). Trying to do run rt2800_get_gain_calibration_delta() when this
is not appropriate on particular chip gives bogus result of TX power
and can make connection unstable.

This is follow up to commit 8c8d2017ba
"rt2800: fix RT5390 & RT3290 TX power settings regression". On that
commit we avoid setting BBP_R1 register, but the real problem is wrong
temperature compensation calculation.
