- This version has support for the new Intel Avoton systems, including 2.5Gb support, further it now has IPv6/TSO6 support as well. Shared code has been updated where necessary as well. Thanks to my new assistant Eric Joyner for doing the transmit path changes to bring in the IPv6/TSO6 support. Thanks to Gleb for catching the one bug and change needed in NETMAP. Approved by: re
