Machine: i386
>Description:
	The GA621 is a fibre gigabit card using the National Semiconductor
chipset supported by the gsip driver. The driver recognises the card and
configures it thus:

gsip0 at pci2 dev 1 function 0: NatSemi DP83820 Gigabit Ethernet, rev 00
gsip0: interrupting at irq 11
gsip0: Ethernet address 00:40:f4:29:5e:d1
gsip0: 64-bit PCI slot detected, using 64-bit data transfers
gsip0: using ten-bit interface
ukphy0 at gsip0 phy 0: Generic IEEE 802.3u media interface
ukphy0: OUI 0x000000, model 0x0000, rev. 0
ukphy0: 1000baseSX, 1000baseSX-FDX, auto

With the card connected to a cisco gigbit switch and the link configured
to be up the card reports no carrier. The link light on the card appears
to be on implying it can see a carrier from the cisco box. The cisco link
light remains off. This state of affairs remains the same for all the
possible media/mediaopt combinations. e.g

gsip0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	capabilities=7<IP4CSUM,TCP4CSUM,UDP4CSUM>
	enabled=0<>
	address: 00:40:f4:29:5e:d1
	media: Ethernet 1000baseSX full-duplex
	status: no carrier
	inet 10.0.0.1 netmask 0xffffff00 broadcast 10.0.0.255
	inet6 fe80::240:f4ff:fe29:5ed1%gsip0 prefixlen 64 scopeid 0x1
>How-To-Repeat:
Insert a Netgear GA621 in a system. load NetBSD-current. Observe you
cannot get the link to pass packets
>Fix:
none supplied (sorry).

The card works fine with FreeBSD 5.0 - but we want to use NetBSD!

The problem looks to be with the handling of the PHY - the OUI etc being
reported as all zeros looks suspicious. The interface chip between the NS
controller is made by Aligent (sp?) and appears from the data sheet to be a
fairly dumb convertor which drives the fibre laser - it is not programmable.

Initially I thought I might be able to fix it, but long hours reading the
code and the NS data sheet show I have a bit more to learn on the relationship
between the driver layer and phy layer :-) Help!

 First of all, please add the "gentbi" driver to your kernel (it's a PHY 
 driver; I guess I've forgotten to add it to GENERIC).

 Secondly, I had a GA621 for a while, and was not able to get it 
 working.  I no longer have access to that hardware.

 I would very much appreciate if you could try and track down the 
 problem.

 Jason, thanks for the fast response! I have added the gentbi phy. The
 dmesg now reports:

 gsip0 at pci2 dev 1 function 0: NatSemi DP83820 Gigabit Ethernet, rev 00
 gsip0: interrupting at irq 11
 gsip0: Ethernet address 00:40:f4:29:5e:d1
 gsip0: 64-bit PCI slot detected, using 64-bit data transfers
 gsip0: using ten-bit interface
 gentbi0 at gsip0 phy 0: Generic ten-bit interface, rev. 0
 gentbi0: 1000baseSX, 1000baseSX-FDX, auto

 However the symptoms remain the same. The link light on the card is
 off when connected to the gigabit switch. If I autoconfig the interface
 up it stays off (media auto). Setting the media to 1000baseSX (either
 duplex) turns the link light on. The switch still thinks the link is
 dead.

 I'll have another poke around the source and see if I can add some
 debugging. My guess is the card is not setting the carrier output on
 and this means media autoselect will not config the card properly.
 Forcing the media to be 1000baseSX means the card correctly sees the
 carrier from the switch and sets the link light on.
