Unable to create the file /sys/class/net//device/sriov_totalvfs file in Ubuntu 22.04

pk flag

I gave all permissions to all files and folders in /sys/ directory, but still I'm unable to create any file in the /sys/ directory too in Ubuntu 22.04. I'm trying to create an sr-iov interface, when I added configuration according to SRIOV support in netplan but it is asking for the above file (mentioned in the title).

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.
