[LU-13781] Local NI selection needs to be restricted on the net of the next-hop

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.15.0
• Severity: 3
• Assignee: Chris Horn
• Reporter: Chris Horn

Description

In lnet_handle_find_routed_path(), after we pick the best_route we assign

local_lnet = best_route->lr_lnet;

And then use local_lnet to lookup the best_ni, but the net we need to restrict on isn't lr_lnet, it's LNET_NIDNET(gwni->lpni_nid).
