When using per channel DMA interrupts the transmit interrupt (TI) and the
receive interrupt (RI) are masked off so as to not generate an interrupt
to the main ISR. However, should another interrupt fire for the DMA channel
that is handled by the main ISR the TI/RI bits can still be set. This
will cause the wrong and uninitialized napi structure to be used causing a
panic. Add a check to be sure per channel DMA interrupts are not enabled
before acting on those bit flags.

Implement the power on/off recommended procedure for the Single GPHY we
have on our Starfighter 2 switch. In order to make sure we get proper
LED link/activity signaling during suspend, switch the link indication
from the Switch/MAC to the PHY.
Finally, since the GPHY needs to be reset to be put in low power mode,
we will loose any context applied to it: workarounds, EEE etc.. so we
need to call phy_init_hw() to get our fixups re-applied successfully.

There are a couple bugs with the error handling in this function.
1) If we can't allocate "rx_ring->rx_skbuff" then we should call
dma_free_coherent() but we don't.
2) free_rx_ring() frees "rx_ring->rx_skbuff_dma" and "rx_ring->rx_skbuff"
so calling it in a loop causes a double free.
Also it was a bit confusing how we sometimes freed things before doing
the goto. I've cleaned it up so it does error handling in normal kernel
style.

Sometimes while CPU have some load and ath5k doing the wireless
interface reset the whole WiSoC completely freezes. Set of tests shows
that using atomic delay function while we wait interface reset helps to
avoid such freezes.
The easiest way to reproduce this issue: create a station interface,
start continous scan with wpa_supplicant and load CPU by something. Or
just create multiple station interfaces and put them all in continous
scan.
This patch partially reverts the commit 1846ac3dbe ("ath5k: Use
usleep_range where possible"), which replaces initial udelay()
by usleep_range().
I do not know actual source of this issue, but all looks like that HW
freeze is caused by transaction on internal SoC bus, while wireless
block is in reset state.
Also I should note that I do not know how many chips are affected, but I
did not see this issue with chips, other than AR5312.

The hardware and firmware for the RTL8192EE utilize a FIFO list of
descriptors. There were some problems with the initial implementation.
The worst of these failed to detect that the FIFO was becoming full,
which led to the device needing to be power cycled. As this condition
is not relevant to most of the devices supported by rtlwifi, a callback
routine was added to detect this situation. This patch implements the
necessary changes in the pci handler, and the linkage into the appropriate
rtl8192ee routine.

This change combines the reset and watchdog tasklets into a single task.
The advantage of this is that we can avoid multiple schedules of the reset
task when we have a reset event needed due to either the mailbox going down
or transmit packets being present on a link down.

This patch updates the ordering of the shutdown path so that we attempt to
shutdown the rings more gracefully. Basically the big changes are that we
shutdown the main Rx filter in the case of Rx and we set the carrier_off
state in the case of Tx so that packets stop being delivered from outside
the driver. Then we shut down interrupts and NAPI. Finally we stop the
rings from performing DMA and clean them. This is a bit more graceful than
the previous path.
