| Subject: ath9k_htc: do some initial hardware configuration |
| |
| From: Oleksij Rempel <linux@rempel-privat.de> |
| |
| commit dc2a87f519a4d8cb376ab54f22b6b98a943b51ce upstream. |
| |
| Currently we configure harwdare and clock, only after |
| interface start. In this case, if we reload module or |
| reboot PC without configuring adapter, firmware will freeze. |
| There is no software way to reset adpter. |
| |
| This patch add initial configuration and set it in |
| disabled state, to avoid this freeze. Behaviour of this patch |
| should be similar to: ifconfig wlan0 up; ifconfig wlan0 down. |
