Gigabit Ethernet under Solaris

Gigabit Ethernet under Solaris

Does Solaris 7 (on the Intel platform) support any Gigabit Ethernet
PCI adapters (preferably with 802.1Q)?  I couldn't find any in the
HCL, but maybe I didn't look in the right place.

We have a Sun E4500, Solaris 2.6, with a gigabit nic installed.

We have the switch port (Cisco 6500, i believe) set at 1000 fdx as

The problem is this, inbound traffic gets only about a 6000 Kbytes/sec
rate, whereas the outbound goes at about 20000 Kbytes/sec.

Does anyone have any ideas why this would occur?  I've searched
Sunsolve and came up with nothing.

Thanks in advance,
