It won't be possible for me.
Relying on the current rte_log_register is buggy with shared builds,
as drivers are calling rte_log_register, then impose a default level
without caring about what the user passed.
So if we introduce a RTE_LOG_REGISTER macro now at least this must be fixed too.
What I wanted to do:
- merge rte_log_register_and_pick_level() (experimental) into
rte_log_register, doing this should be fine from my pov,
- reconsider the relevance of a fallback logtype when registration fails,
- shoot the default level per component thing: levels meaning is
fragmented across the drivers/libraries because of it, but this will
open a big box of stuff,
