Subject: [PATCH net v1] octeon_ep: initialise control mbox tasks before using APIs
Date:   Sat, 2 Dec 2023 07:08:07 -0800
Message-ID: <20231202150807.2571103-1-srasheed@marvell.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

Precedence: bulk

Do INIT_WORK for the various workqueue tasks before the first
invocation of any control net APIs. Since octep_ctrl_net_get_info
was called before the control net receive work task was even
initialised, the function call wasn't returning actual firmware
info queried from Octeon.

Fixes: 8d6198a14e2b ("octeon_ep: support to fetch firmware info")
