Modified Files:
src/share/man/man4: micphy.4
src/sys/dev/mii: micphy.c
Log Message:
Add support for KSZ80[0456]1, KSZ8721, KSZ9[01]31, KS8731 and KSZ9477.
It also supports LAN7430's internal PHY. First wrote by nisimura@ and added
some device support by me. Not tested well.

-.Nd Micrel KSZ9021 10/100/1000 PHY driver
+.Nd Micrel KSZ8xxx 10/100 and KSZ9xxx 10/100/1000 PHY driver
.Sh SYNOPSIS
.Cd "micphy* at mii? phy ?"
.Sh DESCRIPTION
The
.Nm
-driver currently supports only Micrel KSZ9021RN PHY.
+driver currently supports KSZ80[2345689]1, KSZ87[23]x, KSZ90[23]1, KSZ9131 and
+KSZ9477.
+It also supports LAN7430's internal PHY.
The driver has a fixup for
.Xr evbarm/cpsw 4
which requires Gig-E PHYs to adjust RGMII signal timing.
