DPDK now supports > 64 lcores. So all code using/assuming a 64 bit

is broken.
Good point. Is there a TODO-list where such a general review request
can be filed, or should we just file it as a system-wide bug in
Bugzilla?
Nonetheless, I think this one-line fix should be accepted as a short
term solution.
Hi Morten,
I suspect there can be more places that testpmd assumes
max core number is 64, someone needs to spend time to
analyze and fix it.
My point exactly. Someone needs to spend time to analyze all DPDK libraries and
applications, and fix it where appropriate. Where do we register this required
effort, so it can be picked up by someone?
testpmd is an application and it has its own restrictions,
I *assumed* libraries are safe and restriction is only in
testpmd, but may be better to verify this as well.
Also, it should probably be mentioned as a known bug in the 22.03 release notes.
