TODO
- src/vppinfra/cache.h - aarch64 is always 128B cache block size
- src/vppinfra/cpu.[ch] - need ARM feature detection & "show cpu" output
- src/vppinfra/time.[ch] - review ARM architected timer / use cntfrq_el0 instead of estimation
- src/vppinfra/smp.h - use "isb" or "yield" inst
- src/vppinfra/byte_order.h - use "rev" inst
- review __sync use for non-x86/TSO machines; "TCP shared-memory fifos, event logger, etc."
- bihash_8_8.h - crc32 vs xxhash
- string.h - memcpy (inlined by compiler) perf
- SIMD
- quad loop / dual loop optimizations e.g. l2_forward() - hide memory latency
