Actually we've seen this bug before. At the time it was caused by FW
requests for dummy packets during PLT mode, which forced us to issue
Tx..
It was fixed in the FW, but I'm not sure this was ever upstreamed
(customer specific fix, etc). Anyway it's pretty safe to disable the
Tx watchdog during PLT - try something like this:
void wl12xx_rearm_tx_watchdog_locked(struct wl1271 *wl)
{
if (wl->plt)
return;
