> Subject: [PATCH] examples/l3fwd: remove useless reloads in EM main loop
> 
> This patch aligns the l3fwd EM code with the changes made to LPM in commit
> 74fb854a3de6 ("examples/l3fwd: remove useless reloads in LPM main loop").
> This change ensures the compiler knows that the lcore config variables are
> constant values and the compiler will then optimize the code accordingly.
