More likely to be a problem with the network card.

# ifconfig em0
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
         options=3<rxcsum,txcsum>
         inet X.X.X.X netmask 0xffffff00 broadcast X.X.X.X
         ether 00:07:e9:0f:ea:2e
         media: Ethernet autoselect (1000baseTX <full-duplex>)
