Merge branch 'net-800Gbps-support'
Petr Machata says:
====================
net: Add support for 800Gbps speed
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.
