Description of problem:
I have a TP-Link TL-WN821N v3 USB dongle that overheats and shuts itself specially under heavy operations. Googling a bit I've managed to figure out that it is possible to fix this by executing:
# iwconfig wlp0s26f7u3 txpower 12

I wonder if this option can be set by default.

Version-Release number of selected component (if applicable):
$ uname -rsv
Linux 3.12.8-300.fc20.x86_64 #1 SMP Thu Jan 16 01:07:50 UTC 2014

How reproducible:
Most times, if using a heavy load on the device (try a couple of bittorrents for a couple of minutes)

Steps to Reproduce:
1. Put the network interface under heavy load.
2. Wait long enough

USB device info:
Bus 001 Device 007: ID 0cf3:7015 Atheros Communications, Inc. TP-Link TL-WN821N v3 / TL-WN822N v2 802.11n [Atheros AR7010+AR9287]
