vppinfra: bihash improvements
Template instances can allocate BIHASH_KVP_PER_PAGE data records tangent to the bucket, to remove a dependent read / prefetch. Template instances can ask for immediate memory allocation, to avoid several branches in the lookup path. Clean up l2 fib, gpb plugin codes: use clib_bihash_get_bucket(...) Use hugepages for bihash allocation arenas Type: improvement Signed-off-by: Dave Barach <dave@barachs.net> Signed-off-by: Damjan Marion <damarion@cisco.com> Change-Id: I92fc11bc58e48d84e2d61f44580916dd1c56361c
