b43: HT-PHY: upload PHY values when switching channel
After calibrating radio you can find few PHY writes in MMIO dumps:
phy_read(0x0009) -> 0x0000
phy_write(0x01ce) <- 0x03dd
phy_write(0x01cf) <- 0x03d9
phy_write(0x01d0) <- 0x03d5
phy_write(0x01d1) <- 0x0424
phy_write(0x01d2) <- 0x0429
phy_write(0x01d3) <- 0x042d
By comparing to N-PHY code we found out that they are PHY tables for
channel switching plus band info read at the beginning.

mac80211: dynamic PS - don't enter PS when TX frames are pending
Use the tx_frames_pending() driver callback to determine if Tx frames are

to avoid interrupting Tx traffic.
The commit e8306f989483e4b97a8b37dd268de6c8c6f35e75 enabled this

ath9k_hw: Fix false tx hung detection in AR9003 chips
The edma based (AR9003 family) chips update tx status
descriptors in a common ring buffer for all transmitted
frames. Whenever tx interrupt is raised, the descriptors
are processed and tx status index is moved.
The complete tx stauts ring are updated with beacons tx status
when there are no data frames to be sent for a period of time.
In this state, transmitting data frames causes the driver to
wait for the tx status on an incorrect tx status index though
the status was updated by hw properly. The driver detects this
condition as a h/w hang and does unnecessary chip resets.
This issue was orginally reported in adhoc mode while sending

To achieve this, add a sequence counter to the netlink

To find masks and sets, MMIO hacks were used to fool closed driver.

Whereas replugging device make it functional. To solve that problem
force reset device during probe.
With patch messages are gone. Unfortunately device may sometimes
still does not operate correctly after module reload (fail to receive
data after associate), but such cases are rarer than without the patch.

rt2x00: fix possible memory corruption in case of invalid rxdesc.size
Sometimes rxdesc descriptor provided by hardware contains invalid
(random) data. For example rxdesc.size can be bigger than actual
size of the buffer. When this happen rt2x00crypto_rx_insert_iv()
corrupt memory doing memmove outside of buffer boundaries.

b43: HT-PHY: switch radio to requested channel
Switching channel happens after specific SHM write to B43_SHM_SH_CHAN.
This is the way we found it in BCM4331 MMIO dumps. By comparing with
N-PHY code we noticed there is routing used for SYN and TX/RX.
