[PATCH 00/11] Fixes for clang 15

[David Marchand]

Fedora 37 has just been released with clang 15.
The latter seems more picky wrt unused variable.

Fixes have been tested in GHA with a simple patch I used in my own repo:
https://github.com/david-marchand/dpdk/commit/82cd57ae5490
https://github.com/david-marchand/dpdk/actions/runs/3495454457
