Subject: Re: [PATCH 1/3] [NET_BATCH] Introduce batching interface

Hi Jamal,

If you don't mind, I am trying to run your approach vs mine to get some
results
for comparison.

For starters, I am having issues with iperf when using your infrastructure
code with
my IPoIB driver - about 100MB is sent and then everything stops for some
reason.
The changes in the IPoIB driver that I made to support batching is to set
BTX, set
xmit_win, and dynamically reduce xmit_win on every xmit and increase
xmit_win on
every xmit completion. Is there anything else that is required from the
driver?

thanks,

- KK
