If you try with a DELAY=3D3000 (or 5000), what happens ?

Do you have TX pause enabled ? If yes, try to disable pauses.

# ethtool -a eth0
Pause parameters for eth0:
Autonegotiate:	on
RX:		on
TX:		on

# ethtool -A eth0 rx off tx off
# ethtool -a eth0
Pause parameters for eth0:
Autonegotiate:	on
RX:		off
TX:		off
