Re: [net-next 06/17] i40e: Convert CEE App TLV selector to IEEE selector

From: Greg Bowers <redacted>

Changes the parsing of CEE App TLVs to fill in the App selector in struct
i40e_dcbx_config with the IEEE App selector so the caller doesn't have to
consider whether the App came from a CEE or IEEE DCBX negotiation.
