First thing is to decide whether the fix is relevant to 21.11 branch. It 
may have been that the wrong Fixes: tag was used, or part of the fix 
relies on some code not in 21.11 that means it's not feasible to backport.

You can then rebase to 21.11 branch, and check the build. The 21.11 repo 
is here https://git.dpdk.org/dpdk-stable/log/?h=21.11

However, it can be wiser to rebase to the staging post as there is often 
additional commits there that are in the process of being pushed to 
dpdk.org. https://github.com/kevintraynor/dpdk-stable.git

You can send to stable at dpdk.org with [PATCH 21.11] in the subject. See 
below for details. No harm to Cc: me and bluca at debian.org , just to make 
sure we catch it.

thanks,
Kevin.
