[LU-13790] socklnd: NID to interface mapping issues

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.14.0
• Severity: 3
• Assignee: Serguei Smirnov
• Reporter: Serguei Smirnov

Description

Testing showed that NID to interface mapping was still wrong after LU-13566 landed. The following procedure was used to reproduce:

# lnetctl lnet configure
# lnetctl net add --net tcp --if eth0,eth1,eth2
# lnetctl discover <MR peer NID>
# lnetctl ping <MR peer NID> 

Discovery would succeed, but first ping would fail as a NID on an interface other than the first would be picked to send out the ping and the mapping for the NID was wrong.
