Subject: [PATCH net-next ] i40evf: Rename i40e_ptype_lookup i40evf_ptype_lookup

From: [email-masked] (Eric W. Biederman)

When compiling the i40e and the i40evf driver into the same kernel I get:
LD      drivers/net/ethernet/intel/built-in.o
drivers/net/ethernet/intel/i40evf/built-in.o:(.data+0x300): multiple definition of `i40e_ptype_lookup'
drivers/net/ethernet/intel/i40e/built-in.o:(.data+0x780): first defined here
make[3]: *** [drivers/net/ethernet/intel/built-in.o] Error 1
make[2]: *** [drivers/net/ethernet/intel] Error 2
make[1]: *** [drivers/net/ethernet/] Error 2
make: *** [sub-make] Error 2

Fix this by renaming the i40evf version of this structure from
i40e_ptype_lookup to i40evf_ptype_lookup.

This build failure was introduced in:

    i40e/i40evf: i40e implementation for skb_set_hash

    Original comment from Tom Herbert <[email-masked]>

       Drivers should call skb_set_hash to set the hash and its type
       in an skbuff.

    This patch builds upon Tom's original implementation and adds
    the L4 type return when we know it is an L4 hash.
    This requires use of the ptype decoder ring, so enable it.
