Subject: [PATCH net-next 1/2] ice: Add support for 100G KR2/CR2/SR2 link reporting
Date: Wed, 23 Nov 2022 16:55:43 +0100	[thread overview]
Message-ID: <20221123155544.1660952-1-przemyslaw.kitszel@intel.com> (raw)

From: Anirudh Venkataramanan <anirudh.venkataramanan@intel.com>

Commit 2736d94f351b ("ethtool: Added support for 50Gbps per lane link modes")
in v5.1 added (among other things) support for 100G CR2/KR2/SR2 link modes.
Advertise these link modes if the firmware reports the corresponding PHY types.
