2018-05-25	bond: performance harvesting	Steven	1	-0/+2
	- hash is great. But it is a bit too slow for the DP. Use direct array indexing to quickly retrieve the slave interface. - the algorithm used by flow hash is great. But it is a bit too slow for the DP. Use l2_hash_hash() extracted from lb_hash.h which ECMP is using. It makes use of intrinsic crc32 instruction set. - shortcut modulo arithmetic when the operand is 2**x (where x up to 4) to avoid division instruction. - special case for link count == 1 in bond_tx_fn() - use clib_mem_unaligned to access data for the packet to avoid alignment error - Fix some typos for packet tracing.

2017-12-16	Use crc32 wrapper (VPP-1086)	Gabriel Ganne	1	-0/+5
	This allows arm platforms to also take advantage of crc32 hardware acceleration. * add a wrapper for crc32_u64. It's the only one really used. Using it instead of a call to clib_crc32c() eases building symmetrical hash functions. * replace #ifdef on SSE4 by a test on clib_crc32c_uses_intrinsics. Note: keep the test on i386 * fix typo in lb test log Change-Id: I03a0897b70f6c1717e6901d93cf0fe024d5facb5 Signed-off-by: Gabriel Ganne <gabriel.ganne@enea.com>

2017-06-12	Remove calls to crc_u32 and add clib_crc32c for armv8+crc	Christophe Fontaine	1	-1/+25
	crc_u32 was not defined for non x86_64 with SSE4.2 processors. Calls to "crc_u32" are removed and replaced by either a call to clib_crc32c or a call to clib_xxhash, as the result is not used as a check value but as a hash.
