Subject: [PATCH v9 04/13] lpfc: vmid: Add the datastructure for supporting VMID in lpfc
Date: Wed,  7 Apr 2021 04:36:28 +0530
Message-ID: <1617750397-26466-5-git-send-email-muneendra.kumar@broadcom.com> (raw)
In-Reply-To: <1617750397-26466-1-git-send-email-muneendra.kumar@broadcom.com>

From: Gaurav Srivastava <gaurav.srivastava@broadcom.com>

This patch adds the primary datastructures needed to implement VMID
in lpfc driver. It maintains the capability, current state,
hash table for the vmid/appid along with other information.
The implementation supports the two versions of vmid implementation
(app header and priority tagging)
