  Support enabling/disabling VF MAC anti-spoofing from
PF.
User can call the API on PF to enable/disable a specific
VF's MAC anti-spoofing.

Why need to call rte_eth_dev_info_get in driver?

Vf_id is already be checked by below, even I prefer :
if (vf_id > pf->vf_num - 1 || !pf->vfs)
to be
if (!pf->vfs  || vf_id > pf->vf_num - 1)
or if (!pf->vfs  || vf_id >= pf->vf_num)

Agree, I'll remove the max_vfs check.

If fails, will you revert the info in vsi struct?

Please return eth dev lib error code, but not I40E_XXX

Will not. Just leverage the existing behavior. I think it has some good side as user should not try it again and again if not success.

Yes, will change it.
