It depends on hardware, 1G/10G hardware supports 128 reta size only, 40G hardware supports 512 or 128 depends on hardware configuration, 40G VF hardware supports 64.

So maybe it should be the responsibility of the driver to use the right value. This kind of hardware differences should be abstracted for the application.

Yes, the size can be gotten by ops of 'dev_infos_get'.

Now do not think explain what value is allowed for the functions in ethdev layer, as it might be hardware specific.

The problem is that we don't know which value is supported for each driver. You should add a comment like this: /**@{ * Some RSS RETA sizes may be not supported by some drivers. * Check in the PMD documentation. */ #define ETH_RSS_RETA_SIZE_64 64 #define ETH_RSS_RETA_SIZE_128 128 #define ETH_RSS_RETA_SIZE_512 512 /**@}*/ And then add some comments in the PMD to describe the supported sizes. > > Maybe that some comments are needed here. > > Comments might not be needed, as their names tell us what they are clearly.

We just have to keep in mind that the API reference for users is in doxygen. Some details are obvious for you but not clear for the user, especially if he doesn't care about i40e.

So the end users could know the reta size of each NIC by reading its datasheet, or call that function to query the size directly. The macros defined here let the reta size more straightforward, and easy to use. OK, it is good to add some annotations here.
