details: https://anonhg.NetBSD.org/src/rev/e0b90d1148ba
branches: trunk
changeset: 362625:e0b90d1148ba

description:
- All of Marvell PHY's registers from addr 0x0 to 0xf conforms IEEE 802.3
specification, so those register definitions are not required. Use mii.h's
definitions. Note that E1000_ER_PAR_DETECT_FAULT should be 0x0010 instead of
0x0100(typo).
- Restore code for BMCR_ISO which was removed in makphy.c rev. 1.44
- Whitespace fix.
