RE: ath10k driver and firmware upgrade

["Shu, Nick" <Nick.Shu@spirent.com>]

Thanks, All:
I did get the valid MAC after using firmware 10.1.467.2-1.
But if you look at the firmware site instruction, it says that this one is for AP, not for STA, that's why I picked it.
Anyway, glad to solve the problem with help from you all.

Nick

Like Ben said, if you still see 00:03:07:12:34:56 you should use firmware version 10.1.467.2-1.

I added some tips to the wiki:

----------------------------------------------------------------------
To check that you are really using ath10k from backports make sure that compat module is loaded and ath10k_pci module uses it:

$ lsmod | grep compat
compat                 36104  6 iwldvm,iwlwifi,ath10k_pci,ath10k_core,mac80211,cfg80211

To check version of backports project:

$ dmesg | grep backport
[   23.210662] Loading modules backported from Linux version next-20140221-0-gfaa2e6f
[   23.210665] Backport generated by backports.git
backports-20140221-0-g8e94650

The initramfs issues look odd, I haven't seen those before. But otherwise this looks good.

The problem is that firmware 999.999.0.636 doesn't support all hw versions, that's why you need to use firmware from 10.1 branch.
