I see a failure in the loongarch CI.

Running binary with
argv[]:'/home/zhoumin/dpdk/build/app/test/dpdk-test'
'--file-prefix=eal_flags_c_opt_autotest' '--proc-type=secondary'
'--lcores' '0-1,2@(5-7),(3-5)@(0,2),(0,6),7'
Error - process did not run ok with valid corelist value
Test Failed

The logs don't give the full picture (though it is not LoongArch CI fault).

I tried to read back on past mail exchanges about the loongarch
server, but I did not find the info.
I suspect cores 5 to 7 belong to different numa nodes, can you confirm?


I'll post a new revision to account for this case.
