Hi Pablo,

2015-08-07 10:08, Pablo de Lara:

There are 3 things wrong here.

1/ We must absolutely avoid compile-time paths:
	#if (ENABLE_MULTI_BUFFER_OPTIMIZE == 1)                                                                          
	#if (APP_LOOKUP_METHOD == APP_LOOKUP_EXACT_MATCH)
It makes test coverage too hard to track.

2/ When replacing a function, grepping it is a must have.
-simple_ipv6_fwd_4pkts(struct rte_mbuf* m[4], uint8_t portid, struct lcore_conf *qconf)
+simple_ipv6_fwd_8pkts(struct rte_mbuf *m[8], uint8_t portid, struct lcore_conf *qconf)
So this change would be straight forward:
> -						simple_ipv6_fwd_4pkts(&pkts_burst[j],
> +						simple_ipv6_fwd_8pkts(&pkts_burst[j],

3/ The above commit makes also this wrong replacement:
-                                               simple_ipv4_fwd_4pkts(&pkts_burst[j],
+                                               simple_ipv8_fwd_4pkts(&pkts_burst[j],
It is still not fixed.

Please send a v2 for this last typo. Thanks
