Message-Id: <20220704054114.22582-1-matt@traverse.com.au> Date: Mon, 4 Jul 2022 05:41:12 +0000 From: Mathew McBride <matt@...verse.com.au> To: Michal Kubecek <mkubecek@...e.cz> Cc: netdev@...r.kernel.org, Mathew McBride <matt@...verse.com.au> Subject: [PATCH ethtool 0/2] Add JSON support for SFP EEPROM dump This patch adds JSON output support to ethtool's -m option, useful for presenting transceiver module option in a web interface. An example frontend can be found here, for OpenWrt's LuCI: https://gitlab.com/traversetech/muvirt-feed/-/tree/master/sfp-diagnostics-luci You can find samples of the output, plus a screenshot here: 10GBASE-LR SFP: https://gitlab.com/-/snippets/2364354 1/10GBASE-LR dual mode SFP https://gist.github.com/mcbridematt/7921c795c4835afa807d8f83cc132401 I have tried to make the JSON format easy to consume by including both the original field values and full text descriptions, so any consumer of the JSON output doesn't need to replicate ethtool's rendering logic. I'm open to any suggestions on how the structure of the JSON output could be improved.
