memebers used in the switch path come first!
dpo_id_t* load_balance_t_::lb_buckets |
Vector of buckets containing the next DPOs, sized as lbo_num.

dpo_id_t load_balance_t_::lb_buckets_inline[LB_NUM_INLINE_BUCKETS] |
The rest of the cache line is used for buckets.
In the common case where there there are less than 4 buckets, then the buckets are on the same cachlie and we save ourselves a pointer dereferance in the data-path.

flow_hash_config_t load_balance_t_::lb_hash_config |

this is a u16

u32 load_balance_t_::lb_locks |
The number of locks, which is approximately the number of users, of this load-balance.
Load-balance objects of via-entries are heavily shared by recursives, so the lock count is a u32.
