Recovery from ath10k errors

[Ann Lo]

Hello,

Is there a recommended solution to recover from ath10k errors without
reboot? Example errors are:

- Repeated occurrences of "ath10k: SWBA overrun on vdev 0" leading to
other errors.

It appears that ath10k is in a strange state when errors happen. If we
use "modprobe -r ath10k_pci", this call just hangs. (The ifconfig
command hangs too).

We use kernel version 3.14.28. We have tried both Qualcomm firmware
999.999.0.636 and 10.1.467.3-1. Our hardware is WLE900VX.

Thanks,
Ann
