Subject: [PATCH v4 01/40] fsi: hub: Set master index to link number plus one
Date: Wed, 5 Jun 2024 16:22:33 -0500 [thread overview]
Message-ID: <20240605212312.349188-2-eajames@linux.ibm.com> (raw)
In-Reply-To: <20240605212312.349188-1-eajames@linux.ibm.com>
Hub master indexing is problematic if a hub is rescanned while the root
master is being rescanned. Therefore, request a specific index in the hub
driver.
