Subject: [PATCH net-next v3 2/4] net: ethtool: Add support for 80Gbps speed
Date: Thu, 15 Jan 2026 12:56:44 +0100 [thread overview]
Message-ID: <20260115115646.328898-3-mika.westerberg@linux.intel.com> (raw)
In-Reply-To: <20260115115646.328898-1-mika.westerberg@linux.intel.com>
USB4 v2 link used in peer-to-peer networking is symmetric 80Gbps so in
order to support reading this link speed, add support for it to ethtool.

I had to update include/linux/phylink.h as well, I hope it's fine to just
put it into middle and changing all the following bits accordingly. These
does not seem to be user-facing.
