The driver doesn't seem to support Jumbo > frames, so my guess is you have to keep the packet size below 1522 bytes. -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 ? -- Ueimor
