Further investigation: auto-negotiation works only after 'iconfig re0 up'
command.
How to reproduce:
1. Connect cross-over cable via re0 at 7.0-box and rl0 at 6.2-box.
1. Do not place any configuration for re0 in rc.conf
2. Boot a 7.0-BETA2 box. Just after reboot re0 does not get UP status.
I see:
# ifconfig re0
re0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM>
ether 00:1a:4d:52:4e:b1
media: Ethernet autoselect (10baseT/UTP <half-duplex>)
status: no carrier
... and in console:
re0: link state changed to DOWN
4. Force re0 UP with ifconfig re0 up. Then re0 starts and auto-negotiation
works:
# ifconfig re0 up
# ifconfig
re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM>
ether 00:1a:4d:52:4e:b1
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active
So this problem turns into problem of automatic start of re0 interface.
Sorry for this inconvenience with negotiation, but issue with automatic
start is actual. Thanks!
