[dts] [PATCH V1] tests/ipfrag:Modify the way to get the core.

[Rami Rosen]

Hi, Zhu,

> Some platforms have a core number less than a fixed value.

Thanks for this patch. You are right, obviously there are platforms with
other combinations than
"2S/2C/2T", and actually I myself run DTS on diifferent platforms than this
and had some issues related to it with various DTS test modules.

 I have a question, though,if I may:
On which platform ( i mean which combination of socket/core/thread in that
platform) did the solution of using cores = self.dut.get_core_listst("all")
instead of the  hard coded "2S/2C/2T" worked  for you for this ipfrag Test
Module?

And a general question to DTS developers/maintainer:  all the DTS test
suites use hard coded values for the S/C/T combination. And obviously this
will fail on certain platforms. Wouldn't it be reasonable to replace all
these occurrences with self.dut.get_core_listst("all") ? Will
self.dut.get_core_listst("all") always work, for any combination of
socket/core/thread ? Will this work for 2S/4C/2T ?

Regards,
Rami Rosen
