Hi Ferruh,

We have a customer who needs it to be on 22.11.x. That is why I put "Cc: stable at dpdk.org" in it.

Another patch, " net/mana: add 32 bit short doorbell", is required to make mana fully
functional  with 32 bit applications. This patch is to fix some build time errors and warnings
when build in 32 bit.  These patches can be independently built and they are addressing
two different issues. So, I put them into two independent patches. 

I have tested it on 32 bit applications. They can run with this patch. Just mana would not
work as the applications still use 64 bit long door bells, which do not work for 32 bit apps.

Thanks,
Wei
