First Atheros cards (before 2413) have MAC and PHY on the same chip and radio on a separate chip, MAC/BB chips are named AR52XX and radio chips RF51XX. Newer Atheros cards have all parts on the same chip, MAC is mostly the same as AR5212 (that's why we mark them as AR5K_AR5212) but PHY and (especially) RF change so the whole chip gets the name of the radio chip (RFX4XX -> ARX4XX). So AR2425 has an AR5212 MAC with minor modifications and an RF2425 radio chip. SREV register marks the whole chip (since it's not only a MAC/BB chip anymore) so this might be confusing. -- GPG ID: 0xD21DB2DB As you read this post global entropy rises.
