details: https://anonhg.NetBSD.org/src/rev/ae43b102fa0f
branches: trunk
changeset: 745800:ae43b102fa0f

description:
- Add the D-Link products, identified by subsystem ID.
- On some variations, the internal PHY is ghosted at #0 and #1. Work
around this by ignoring PHY #0 accesses unless we don't find one, and
then look for one there as a fall-back if we don't detect anything else.
- Fix access width when setting the TxDMAUrgentThresh register.
- Support MBUFTRACE.
