Subject: [PATCH net-next 0/3] Add support for 800Gbps speed
Date: Thu, 20 Oct 2022 17:20:02 +0200 [thread overview]
Message-ID: <cover.1666277135.git.petrm@nvidia.com> (raw)
Amit Cohen <amcohen@nvidia.com> writes:
The next Nvidia Spectrum ASIC will support 800Gbps speed.
The IEEE 802 LAN/MAN Standards Committee already published standards for
800Gbps, see the last update [1] and the list of approved changes [2].
As first phase, add support for 800Gbps over 8 lanes (100Gbps/lane).
In the future 800Gbps over 4 lanes can be supported also.
Extend ethtool to support the relevant PMDs and extend mlxsw and bonding
drivers to support 800Gbps.
Patch set overview:
Patch #1 extends ethtool to support 800Gbps.
Patch #2 extends mlxsw driver to support 800Gbps.
Patch #3 extends bonding driver to support 800Gbps.
