Add to /etc/rc.local :
ifconfig em0 debug
ifconfig em0 media 100baseTX mediaopt full-duplex
For in rc.conf not working these options:
#ifconfig_em0="100baseTX mediaopt full-duplex"
#ifconfig_em0="debug -vlanmtu -vlanhwtag -vlanhwfilter -vlanhwtso -wol"
Now the network card looks like this:
# ifconfig em0 | grep -v inet
em0: flags=8847<UP,BROADCAST,DEBUG,RUNNING,SIMPLEX,MULTICAST> metric 0
mtu 1500
options=219b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_MAGIC>
ether 00:25:90:05:83:7a
nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
media: Ethernet 100baseTX <full-duplex>
status: active
