I am having a few problems getting a Netgear GA621 gigabit card to work. This
has an SX fibre interface. System is running 1.6K from Nov 19th. The card
is detected OK and is reported by the kernel to support 1000baseSX,
1000baseSX-FDX & auto. The card is plugged into a cisco catalyst 6500 which
supports 1000SX in full duplex mode only.

dmesg reports:

'ifconfig gsip0 media 1000baseSX' reports no errors, however while the
card link light comes on, the link is dead as far as the catalyst is
concerned. An 'ifconfig gsip0' reports:

gsip0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500

This looks suspiciously like the PHY is not being handled correctly. Can
anyone suggest where to start looking. I've had a quick poke around
if_sip.c but cannot see anything obvious...

TIA
Dave
