ip: avoid fib lookup for consecutive pkts having same source IP
Type: fix
Fixes: be2286b0
This patch does following:
- If terminating frame has consecutive packets with same source IP, this patch
avoids fib lookup for those packets in ip4-local node. This drops cycle count
for ip4-local node on both ARM and x86. It being done by enabling dead code in
else {} case of ip4_local_check_src_x2() and ip4_local_check_src() functions.
- In case all packets in terminating frame have unique source IP (e.g:
incrementing), ip4-local is costlier by 2 cycles (broadwell)
