Even branch free inlining should save load/store traffic in terms of
stack frame setup and lost optimization opportunities due to alias
analysis (restrict helps with this a bit, but...).

I'd say this is especially true on the send path - I have several
code cases where the send path is doing a batch of work in a
loop.

The rx path, maybe not so much since you generally would rx one thing
and then process..
