Subject: [PATCH v2 5/8] staging: r8188eu: use random default mac address
Date: Mon, 30 Aug 2021 14:15:05 +0200	[thread overview]
Message-ID: <20210830121508.6411-6-straube.linux@gmail.com> (raw)
In-Reply-To: <20210830121508.6411-1-straube.linux@gmail.com>

Use a random default mac address instead of a fixed one to reduce the
likelihood of mac address collision.
