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) Change-Id: I472ddc324716cec8bfe601568b8aeb7565f97ab3 Signed-off-by: Nitin Saxena <nsaxena@marvell.com>
