I read value from the SREV register of AR9582 -- got 0x001c04ff. I looked through the code of ath9k and found out that in this case the revision is 4. So, since AR_SREV_REVISION_9580_10 is defined as 4, I logically concluded that AR_SREV_9580_10 would do the job. But you suspicions turned to be right. I tested AR9580 now and it has the same value as AR9582 in the SREV register -- 0x001c04ff. PCI Subsystem ID is zero on those Mikrotik cards, so it is not useful. Felix, guys, may be somebody have any thoughts how we can distinguish AR9582? Or that a chip has only 2 chains? May be values from other registers? сб, 11 янв. 2020 г. в 13:37, Felix Fietkau <nbd@xxxxxxxx>: > > On 2020-01-10 14:21, Denis Kalashnikov wrote: > > Some of the Mikrotik R11e-2HPnD cards have EEPROM where is > > flashed that a card has 3 chains, but actually all this cards > > have only 2.
