This means that this thread will poll only pinned RX queues My problem is that I have several CPUs spreading on different NUMA nodes. I hope all these CPU can have chance to serve the rxq. However, because the phy NIC only locates on one certain socket node, non-same numa pmd/CPU would be excluded. So I am wondering whether we can have different behavior for phy port rxq: round-robin to all PMDs even the pmd on different NUMA socket. I guess this is a common case, and I believe it would improve rx performance. [Darrell] I agree it would be a common problem and some distribution would seem to make sense, maybe factoring in some favoring of local numa PMDs ? Maybe an optional config to enable ?
