Could you add logic to recoginize IGMP to the software packet type identification
rte_net_get_ptype used by drivers that don't have hardware support.

Also shouldn't this bit be part of RTE_PTYPE_L4_MASK?

If everyone agrees then I can do it as adding IGMP support will reduce
the performance of rte_net_get_ptype() and most of the NIC may not need it.

Opinions?

The RTE_PTYPE_L4_MASK is 0x00000f00 so it is part it. Right?

Then you must add it to the software matcher since most drivers are advertising L4_MASK

Since IGMP is an IP protocol field and the code is already looking for
TCP and UDP, how could adding another else slow it down in any observable way.

Which driver returns .dev_supported_ptypes_get ethdev ops with L4_MASK?
