[dpdk-dev] [PATCH] i40e:Fix for wrong publish of card speed (was mixed between 10G and 40G)

[Ido Barnea (ibarnea)]

Hi Jingjing,
The existing code was obviously wrong. 
For the XL710 it returned: ETH_LINK_SPEED_1G |ETH_LINK_SPEED_10G
And for the X710: ETH_LINK_SPEED_10G |ETH_LINK_SPEED_40G


I did a minimal fix, and swapped the lines.

Any fix that will return the correct values is welcome.
For my purpose your proposal is fine.

You want me to change my patch, or you will do it?

Thanks,
Ido
