Subject: [net-next V2 11/14] net/mlx5: Devcom, Rename paired to ready
Date: Fri, 2 Jun 2023 12:12:58 -0700 [thread overview]
Message-ID: <20230602191301.47004-12-saeed@kernel.org> (raw)
In-Reply-To: <20230602191301.47004-1-saeed@kernel.org>
From: Shay Drory <shayd@nvidia.com>
In downstream patch devcom will provide support for more than two
devices. The term 'paired' will be renamed as 'ready' to convey a
more accurate meaning.
