including:
and RTL8153 USB Gigabit Ethernet devices including:
The RTL8152 contains an integrated Fast Ethernet MAC, which supports both 10 and 100Mbps speeds in either full or half duplex. The RTL8153 has a Gigabit Ethernet MAC and additionally supports 1000Mbps speeds.
It presently provides IPv4/TCPv4/UDPv4/TCPv6/UDPv6 checksumming in hardware. (The earliest 8152 variant only supports this checksumming on transmission; all other variants offer it on both transmission and reception.) It also supports VLAN-sized frames. TSOv4 and v6 offload are not presently supported.
