I am just curious, is this a normal device ID for AR9381 chips or is
this some kind of wrongly programmed EEPROM of TD-W8970?
ath9k driver knows nothing about the 0xABCD device. And according to
wikidevi [1], the normal DevID for AR9381 based devices is 0x0030.

Hi,
Thanks for pointing this out.
It could be that I broke something in the EEPROM on this device
accidentally, I use it for testing since some time. It could also be
that the PCIe controller driver is broken, it is not upstream and not
looking nice.
