[PATCH nf-next 0/4] netfilter: replace u_int*_t with kernel int types (batch 2)

[Carlos Grillet]

This patch series replaces POSIX u_int8_t/u_int16_t with the preferred
kernel types u8/u16 across several netfilter files and updates the
corresponding header definitions.

This continues the work started in:
https://lore.kernel.org/all/20260616182948.96865-1-carlos@carlosgrillet.me

No functional changes.

These port variables are useless and will be removed soon.
