Here is the dmesg using 8.1 (formal release) kernel:

re0 at pci3 dev 0 function 0: RealTek 8100E/8101E/8102E/8102EL PCIe 10/100BaseTX (rev. 0x05)
re0: interrupting at msi2 vec 0
re0: Unknown revision (0x40c00000)
re0: Ethernet address 28:92:4a:29:53:5a
re0: using 256 tx descriptors
ukphy0 at re0 phy 7: OUI 0x00e04c, model 0x0008, rev. 2
ukphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto

So, it is MSI instead of MSI-X.
This is from ifconfig:

re0: flags=0x8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        capabilities=3f80<TSO4,IP4CSUM_Rx,IP4CSUM_Tx,TCP4CSUM_Rx,TCP4CSUM_Tx>
        capabilities=3f80<UDP4CSUM_Rx,UDP4CSUM_Tx>
        enabled=0
        ec_capabilities=3<VLAN_MTU,VLAN_HWTAGGING>
        ec_enabled=0
        address: 28:92:4a:29:53:5a
        inet 192.168.1.27/24 broadcast 192.168.1.255 flags 0x0
        inet6 fe80::2a92:4aff:fe29:535a%re0/64 flags 0x0 scopeid 0x1

I checked again and the NIC is perfectly working in this case.
