difficulty w/ RTE_NEXT_ABI

[Matthew Hall <mhall@mhcomputing.net>]

I was trying to rebase my DPDK onto v2.1.0 and I came across some very 
confusing code in examples/l3fwd/main.c .

So... this code used the RTE_NEXT_ABI macros on a change which does not appear 
to affect the API... on a function that is marked always_inline ???

Maybe I missed something but this seems pointless. An always_inline function 
is going to have to be recompiled in any case.

Now I have no clue what would makes sense for my version of the function 
either... because RTE_NEXT_ABI is a binary on/off but trying to track a 
multi-variate quantity of ABI updates.

For now I guess I have to write it like this inside the RTE_NEXT_ABI:

rfc1812_process(struct ipv4_hdr *ipv4_hdr, uint32_t *dp, uint32_t ptype)

This seems unpleasant and kind of painful. What did I miss here?

Matthew.
