RSS question

Hi! Thank you for releasing drivers with RSS for openwrt!
i can't get the documentation, you set 2 cores for intel i211 2 queues for 2 nic's
For example i have x2 i210 nic's with 4 queues and 2 core 4 thread cpu, should i put RSS=4,8? or 2,4? RSS=x,y?
Hi!
I am not related with this code repository in any manner, but according to the documentation (README file from intel igb driver package):
igb [<option>=<VAL1>,<VAL2>,...]
A value (<VAL#>) must be assigned to each network port in the system supported by this driver.
The values are applied to each instance, in function order.
In the case of two network ports installed in the system having 2-Core CPU the command syntax would be:
igb RSS=2,2
A note regarding HyperThreaded (HT) CPU cores.
In your particular case (2-Core/4-Thread CPU) It is recommended no more than 2 queues per port because for the driver hyper-threads typically add little to no additional performance gain since they are not true cores and they take away from work being done on other CPUs.
