2023-01-18lb: add source ip based sticky load balancingNobuhiro MIKI1-9/+76
This patch adds source ip based sticky session, which is already implemented in many hardware LBs and software LBs. Note that sticky sessions may be reset if the hash is recalculated as ASs are added or deleted. Since this feature is unrelated to the other existing options, the lb_add_del_vip API version has been upgraded to v2 and a new option "src_ip_sticky" has been added.

2019-07-31vppinfra: refactor test_and_set spinlocks to use clib_spinlock_tjaszha031-1/+2
Spinlock performance improved when implemented with compare_and_exchange instead of test_and_set. All instances of test_and_set locks were refactored to use clib_spinlock_t when possible. Some locks e.g. ssvm synchronize between processes rather than threads, so they cannot directly use clib_spinlock_t.

2018-02-02Add L3DSR feature in LB pluginHongjun Ni1-5/+33
L3DSR is used to overcome Layer 2 limitations of Direct Server Return Load Balancing. It maps VIP to DSCP bits, and reuse TOS bits to transfer it to server, and then server will get VIP from DSCP-to-VIP mapping.
