From ab723121a8eade04ecc6bd7116924c359336f4eb Mon Sep 17 00:00:00 2001 From: James Smart Date: Tue, 14 May 2019 14:58:06 -0700 Subject: [PATCH] lpfc: add nvmet discovery_event op support This patch adds support for the nvmet discovery op. When the callback routine is called, the driver will call the routine to generate an RSCN to the port on the other end of the link.
