Member Function Documentation

◆ CLIB_CACHE_LINE_ALIGN_MARK()

bier_imp_t_::CLIB_CACHE_LINE_ALIGN_MARK ( cacheline0 )

Required for pool_get_aligned.

Field Documentation

◆ bi_bits

u8 bier_imp_t_::bi_bits[BIER_HDR_BUCKETS_1024]

The bit string.

This is a memory v. speed tradeoff. We inline here the largest header type so as the bitstring is on the same cacheline as the header.

Definition at line 58 of file bier_imp.h.

◆ bi_dpo

dpo_id_t bier_imp_t_::bi_dpo[FIB_PROTOCOL_IP_MAX]

The DPO contirubted from the resolving BIER table.

One per-IP protocol. This allows us to share a BIER imposition object for a IPv4 and IPv6 mfib path.

Definition at line 45 of file bier_imp.h.

◆ bi_hdr

bier_hdr_t bier_imp_t_::bi_hdr

The Header to impose.

Definition at line 50 of file bier_imp.h.

◆ bi_locks

u32 bier_imp_t_::bi_locks

number of locks

Definition at line 68 of file bier_imp.h.

◆ bi_tbl

bier_table_id_t bier_imp_t_::bi_tbl

The BIER table into which to forward the post imposed packet.
