I'm using Mellanox ConnectX-5 100 GB NIC, Linux kernel 5.15 and my server has 32 cores (SMT disabled). But in the /sys/net//queues, the number of rx queues is 64, which is double the number of cores of my server? How to fix it

is hyperthreading enabled? – djdomi May 27 '23 at 16:24
no, it was disabled. In case it is enabled, i will have 64 virtual cores and the number of rx queues is 128. I suppose it is because of AF_XDP. – Anh Phan May 29 '23 at 17:33
