Segfault in mlx5 cleanup
http://bugs.dpdk.org/show_bug.cgi?id=1796
Bug ID: 1796
Summary: Segfault in mlx5 cleanup
Product: DPDK
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: other
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
This was caught by GHA when running fast-tests.
FWIW, I saw no recent change on the mlx5 driver.
A small update was done in the order of cleanup operations for multi process
support: 4bc53f8f0d64 ("eal: fix MP socket cleanup").
