[PATCH iwl-next 1/2] i40e: Remove VF MAC types
Posted by Ivan Vecera 2 years, 1 month ago 
The i40e_hw.mac.type cannot to be equal to I40E_MAC_VF or
I40E_MAC_X722_VF so remove helper i40e_is_vf(), simplify
i40e_adminq_init_regs() and remove enums for these VF MAC types.

What about removing those I40E_VF_* defines?
This is their only usage here, right?

Yes, do you want to remove them in this patch? Or follow-up is sufficient?

Wait, do you suggest to use the values directly? That would be
wild even for i40e :)

Ah, sec. This is duplicated in
drivers/net/ethernet/intel/iavf/iavf_register.h. That confused me.

Its possible the iAVF code could be cleaned up too... Historically the
i40e and i40evf duplicated quite some code.

Indeed, in case of i40e they're going be unused after this patch so
there is no point in keeping them, I think.
