Hi Cristian,
Thanks for your quick response. I did a quick test of your hypothesis and it
sort of came out as you mentioned. That is, it went back to ~4Gbps after around
ten minutes with the previous profile I posted.
In another test, I set the pipe token rate to ~20Mbps instead of full line rate
Hi Wei,
Here is another hypothesis for you to consider: if the size of your token

There were two line items on the 2.2 roadmap: Xen Driver and Hyper-V Driver.
Can you provide some more details?

Hi Husainee,
Yes, please try on release 2.1 and do come back to us with your findings. Based
on your findings so far though, looks like this is not a SW issue with the

The macros to check that the function pointers and port ids are valid

However, since they would then become externally visible, we apply
