Bug ID	1271
Summary	Using dumpcap to capture packets with multiple pmds and enabl= e mbuf check can lead to dpdk proc core
Product	DPDK
Version	23.11
Hardware	All
OS	All
Status	UNCONFIRMED
Severity	normal
Priority	Normal
Component	other
Assignee	dev@dpdk.org

Target Milestone	---

When creating a mempool, dumpcap s=
elects the type 'mp_sc' causes thread
insecurity when multiple PMDs in the main process apply for mbuf. If the ch=
eck
of mbuf is enabled at this time, it will cause the process to panic. So, the
type for creating mempool should be 'mp_mc'
