Number of receiving queues is double the number of cores of my server?

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

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.
I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
