ibm_newemac tx problem with jumbo frame enabled

[Prashant Bhole]

Hi,
I have been facing problem with ibm_newemac driver (v3.54).
The board gets disconnected and can not be pinged in between
some heavy network traffic. In my case I am running IOmeter
"All-in-One" 8 threads on the iSCSI target. MTU is 4088.

I found that after executing emac_full_tx_reset(), the board can
be pinged again. Again after some heavy traffic of 5-6 seconds,
traffic stops. This can be repeated after full tx reset.

Is this a known issue? what could cause this?
Any pointers would be greatly appreciated.
