>Description:
With 9.2, media auto selection worked:

With 9.2, media auto selection worked:

# ifconfig tlp0
tlp0: flags=0x8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        ec_capabilities=1<VLAN_MTU>

[   1.0000000] tlp0: 10baseT, 10baseT-FDX, 10base2, 10base5

With the HEAD install kernel, it no longer does:

[ 337.1011682] tlp0: transmit timeout
# ifconfig tlp0
tlp0: flags=0x8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        ec_capabilities=0x1<VLAN_MTU>
        ec_enabled=0

        media: Ethernet autoselect instance 1 (none)
        inet 10.128.0.15/8 broadcast 10.255.255.255 flags 0

Manually configuring it helps:

# ifconfig tlp0 media 100baseTX-FDX
# ifconfig tlp0
tlp0: flags=0x8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        ec_capabilities=0x1<VLAN_MTU>
        ec_enabled=0

Boot the install kernel and try to use the network interface tlp0.
