Subject: linux-next: build failure after merge of the net-next tree

Hi all,

After merging the net-next tree, today's linux-next build (x86_64
allmodconfig) failed like this:

Caused by commit

  1121f6b02e7a ("octeontx2-af: Priority flow control configuration support")

I have used the net-next tree frm next-20220209 for today.
