[dpdk-users] Need help: Generate core list error. rte_eal port num [0] is not match the pciidlist [4]

[Ding Ma]

Really appreciate your help. Two follow-ups:
- it actually works on 48 cores server and do you know why?  (The problem
server is 96 cores)
- which part in config I need to change? (Sorry I am a noob) . Also, I am
using pre-built RPM to install dpdk, do I have to rebuild the RPM on 96
cores server in order to run it on the 96 cores server?
