-1

The driver does not support Jumbo frames because the original 8169 will not
go much beyond 7200 (see r8169.c::SafeMtu and netdev circa 2004 december 7).

/me checks... Apparently it still works a bit.

Sergey, can you 'dmesg | grep XID' and send the output of a lspci as
well as the MTU used during the test ?
