It works with mtu at 1500. If I set mtu to 9000 and send a small ping
(such as 32 bytes), it still works. But when I attempt to transmit a
jumbo frame, by a ping -s 4000, the card drops into a state where no
packet manages to get out anymore. Even a ping -s 32 does not work
Sometimes it says:
bge0: watchdog timeout -- resetting
bge0: block failed to stop: reg 0xc00, bit 0x00000002
