Subject: [PATCH 4/5] net: dsa: b53: allow lower MTUs on BCM5325/5365
Date: Fri, 04 Oct 2024 10:47:20 +0200 [thread overview]
Message-ID: <20241004-b53_jumbo_fixes-v1-4-ce1e54aa7b3c@gmail.com> (raw)
In-Reply-To: <20241004-b53_jumbo_fixes-v1-0-ce1e54aa7b3c@gmail.com>
While BCM5325/5365 do not support jumbo frames, they do support slightly
oversized frames, so do not error out if requesting a supported MTU for
them.
Fixes: 6ae5834b983a ("net: dsa: b53: add MTU configuration support")
