From ad8a260aa80d4dfa9588fd5d23b71ec922f61c8b Mon Sep 17 00:00:00 2001 From: Quinn Tran Date: Wed, 26 Feb 2020 14:40:21 -0800 Subject: [PATCH] scsi: qla2xxx: Set Nport ID for N2N When transitioning from loop to N2N, stale NPort ID is not re-assigned. Stale ID can collide with remote device. This patch will re-assign NPort ID on N2N is detected.
