Re: [PATCH] ethdev: add link speed 400G

[fengchengwen]

Hi Thomas,

  Higher rates are generally implemented with multiple lanes. The lane configuration is
critical to link negotiation success. The number of lanes configured using the ethtool
is provided [1].

 Currently, the community uses only one u32 bit (link_speed) to indicate a rate, which
is not enough.

 It is recommended that the rate be extended to support the configuration of the number
of lanes. Our team plan to develop it target 23.07 version (have not yet been designed).
Maybe other team already developping it (if have please let me know so that we can reduce
invest).

 Beside, as for this patch, I think we could upstream first.

It looks like some testpmd help strings and documentation missed, please
check previous commit as reference:
Commit f6eb39384933 ("ethdev: add 200G link speed")


Also last time release notes also updated for new speed, what about
doing same?
