I'm sorry about my previous email. I forgot to disable HTML formatting.
Been testing the 4.4.1 firmware for around 40 minutes and no
disconnections so far. It's looking great. dmesg tells me it's been
correctly upgraded:
 ath10k_pci 0000:02:00.0: enabling device (0000 -> 0002)

A diff on the previous firmware's dmesg (before moving to
firmware-4.bin) shows the new version:
5c5
