Jack,
I have Intel Gigabit card and FreeBSD-7.0-STABLE recognizes it as following:
...
em0@pci0:0:25:0: class=0x020000 card=0x2800103c chip=0x104a8086
rev=0x02 hdr=0x00
vendor = 'Intel Corporation'
device = '82566DM Gigabit Network Connection'
class = network
subclass = ethernet
...
# uname -an
FreeBSD test.ub.mng.net 7.0-STABLE FreeBSD 7.0-STABLE #0: Thu Jun 5
11:12:34 ULAT 2008
tsgan@test.ub.mng.net:/usr/obj/usr/src/sys/FIREWALL i386
It has some problem, 1000baseTX connection status almost never goes to
active in bridged mode, sometimes
it goes to active but then immediately it goes to no carrier. (The other
end is Cisco4507R, Gigabit Ethernet port)
...
em0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0
mtu 1500
options=198<VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4>
ether 00:0f:fe:82:23:db
media: Ethernet 1000baseTX <full-duplex> (autoselect)
status: no carrier
...
Any idea how to solve this issue?
thanks,
Ganbold
