"ifconfig bge1 media none" does change the PHY status temporarily. I see the following when I run this command:
bge1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM>
ether 00:40:d0:b8:1e:0b
media: Ethernet none
status: no carrier
After a few seconds if I do "ifconfig bge1", it's automagically changed to:
bge1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM>
ether 00:40:d0:b8:1e:0b
media: Ethernet none (1000baseTX <full-duplex>)
status: active
I tried playing around with mediaopt, but PHY status doesn't seem to change permanently.
