4.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Quinn Tran quinn.tran@cavium.com
commit 5c6400536481d9ef44ef94e7bf2c7b8e81534db7 upstream.
This patch fixes issue where driver clears NPort ID map instead of marking handle in use. Once driver clears NPort ID from the database, it can reuse the same NPort ID resulting in a PLOGI failure.
