Thats why the flush flag is always set and the GRO stack does
not work at all. I'm willing to dig deeper into this but I'm unsure
if those fields are filled on sender or receiver side and especially
where in the IPoIB stack.
Maybe I got the reason for that strange ack behaviour during
large
Hi Markus,
As Or already mentioned, it seems that we have accumulations of ip
packets, when GRO is enabled over ib interface, from tcpdump in the
recieve side we can see:
10:09:27.336951 IP 11.134.33.1.41377 11.134.41.1.35957: Flags [.], seq
3795959253:3796023381, ack 2, win 110, length
Hi Erez,
don't you see that behaviour in tcpdump? what kernel are you using?
On server side we have a 3.5 on client side a 3.11 kernel each of them with
kernel standard drivers/modules. I can see the same pattern of GRO
aggregation on the client that you mention but only if I disable TSO for
Hi Markus,
Can you please tell me what is the FW version you have on your ConnectX
cards?
Thanks, Erez

I looked at TSO code earlier this year. IIRC, if TSO is on, the upper
layer (e.g. IP) would just send the super-packet down (to IPOIB) w/out
segmentation (for send); if off, it then does the segmentation (to
match the MTU size) before calling device's send. For GSO, I would
imagine it needs some
11 matches
