2018-11-17IP-punt: add documentation to the API and fix IP address initNeale Ranns2-1/+3

2018-11-15ip4-input: fix prefetch data issue for tunnel decap casesZhiyong Yang1-4/+8
There are two reasons to modify the existing code ip4_input_inline. 1. For many tunnel decap cases, inner ip header or its part is possible in the second cacheline, not first cacheline only after the field "data", and this will cause data cache miss once the second cacheline is needed to access. e.g vxlan-gpe. 2. For most of cases, "data" is the starting address of ethernet header, not IP header. The existing code causes misunderstanding from code readability perspective.

Currently, there are three variants available on aarch64, qdf24xx, thunderx2t99, and cortex-a72. -DCLIB_N_PREFETCHES is passed to source code to select dual/quad implementation. Besides, different compiler options are applied on these critical functions. gcc-7.3.0 reports ICE(internal compiler error) with -mtune=thunderx2t99, so -mtune=thunderx2t99 is enabled only when gcc version is greater than 7.3.0 Cavium ThunderX2, Impermenter 0x43, Part 0x0af -march=armv8-a+crc+crypto -mtune=thunderx2t99 Qualcomm Centriq 2400, Impermenter 0x51, Part 0xc00 -march=armv8.1-a+crc+crypto -mtune=qdf24xx Cortex-A72, Impermenter 0x41, Part 0xd08 -march=armv8-a+crc+crypto -mtune=cortex-a72 Change-Id: Id5649c6325c1e642d0fd42535e3908793b13e02a Signed-off-by: Lijian Zhang <Lijian.Zhang@arm.com> Reviewed-by: Sirshak Das <sirshak.das@arm.com> Reviewed-by: Honnappa Nagarahalli <Honnappa.Nagarahalli@arm.com>

Since the stats aggregation for the stat segment does not use the API, that part is now done on the main thread. (Old stats aggregator is also left in place).
