Tick. The speed bits correspond (they're a little harder to check, it would have been easier for them to be 2 << 9 etc), tick. The speed+duplex bits correspond (same issue with the raw speed bits, defining them as MDIO_LPA_USXGMII_1000 | MDIO_LPA_USXGMII_FULL_DUPLEX would've made them more obvious, but at the expense of being more long winded), tick.
