Problem resolved replacing the motherboard.

ifconfig_em0="inet xxx.xxx.xxx.82/29"

# ifconfig em0 | grep -v inet
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500

options=219b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_MAGIC>
        ether 00:25:90:06:bc:60
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
        media: Ethernet autoselect (100baseTX <full-duplex>)

Note that the default setting network card no options: RXCSUM and TXCSUM!
