 Which mailing list is best for discussions about adding support for a new
 PHY?

 I recently bought a couple of Rosewill RC-400 gigabit Ethernet
interfaces, hoping they would work with NetBSD because they are based on
the Realtek 8169S.  They are recognized by 3.1_STABLE on alpha or i386:

re0 at pci0 dev 14 function 0: RealTek 8169S Single-chip Gigabit Ethernet
re0: interrupting at dec 6600 irq 35
re0: Ethernet address 00:e0:4c:77:79:80
re0: using 512 tx descriptors

Unfortunately, i suspect there might be a problem with the cards' PHY,
which is matched by the Generic PHY driver:


ukphy0 at re0 phy 7: Generic IEEE 802.3u media interface


 I can't get the card to work with my Netgear GS724T gigabit switch, even
when i set the media and mediaopts to "Ethernet 1000baseT full-duplex" and
set the port accordingly on the switch.


 So i suspect the problem may be that the ukphy driver doesn't work well
 with the RC-400's PHY, which is a "TAIMAG IH-002."

 I am not a programmer, but i'm wondering how difficult it would be to try
and write a PHY driver for the IH-002.  The files for the various PHY
drivers are too big.

I don't know about writing a PHY driver, but that chip isn't a PHY;
it's a transfomer. http://www.taimag.com/Products/LAN-IH.htm

According to the re(4) manpage, the 8169S has a built-in PHY. Try adding
rgephy to your kernel config.

Ah, i should have realized that.

 I built a new kernel with:

     rgephy* at mii? phy ?


 And it is recognized during the boot:

re0 at pci0 dev 14 function 0: RealTek 8169S Single-chip
Gigabit Ethernet
re0: interrupting at dec 6600 irq 35
re0: Ethernet address 00:e0:4c:77:79:80
re0: using 512 tx descriptors
rgephy0 at re0 phy 7: RTL8169S/8110S 1000BASE-T media
interface, rev. 0

 But i can't get it to work (via 'ifconfig re0 media
100baseTX mediaopt
full-duplex' for example) with the switch at anything other
than 10baseT.

 (This is NetBSD 3.1.)

Thanks for your help.

Generally speaking, gig e switches demand that you
autonegotiate. Try
it again with autonegotiation instead of nailing it.
