Subject: [PATCH V2 net-next 5/5] net: hns3: add support to query and set lane number by ethtool
From: Hao Chen <chenhao418@...wei.com>
When serdes lane support setting 25Gb/s or 50Gb/s speed and user wants to
set port speed as 50Gb/s, it can be setted as one 50Gb/s serdes lane or
two 25Gb/s serdes lanes.
So, this patch adds support to query and set lane number by ethtool
to satisfy this scenario.
