Looks like this is a reason:
# ifconfig em4
em4: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=19b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4>
ether 00:15:17:80:f5:ee
media: Ethernet autoselect
status: no carrier
# ifconfig em5
em5: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=19b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4>
ether 00:15:17:80:f5:ef
media: Ethernet autoselect
status: no carrier
No 64bits counters returned for interfaces bellow them.
