Subject: [PATCH 0/3] Add support for speed in MANA ethtool
Date: Thu, 20 Mar 2025 05:22:18 -0700 [thread overview]
Message-ID: <1742473341-15262-1-git-send-email-ernis@linux.microsoft.com> (raw)
Display speed information of the port via get_link_ksettings
ethtool operation using a HWC command MANA_QUERY_LINK_CONFIG
to fetch the speed information from the hardware.
Add support for mana_set_link_ksettings in MANA ethtool operation.
A HWC command (MANA_SET_BW_CLAMP) is sent to hardware to set
the bandwidth at specified speed.
This feature is not supported by all hardware. For any unsupported
clusters, the speed will be displayed as Unknown.
