[LU-12893] lnet: peer ni selection broken

• Type: Bug
• Resolution: Fixed
• Priority: Critical
• Fix Version/s: Lustre 2.13.0, Lustre 2.12.4
• Severity: 3
• Assignee: Amir Shehata (Inactive)
• Reporter: Amir Shehata (Inactive)

Description

in 2.10.x the peer NID used remains the same for all LNet messages which are part of the same RPC request.

in 2.12 and later, that requirement has been broken. This will cause a performance hit on NUMA architectures.
