🔥 Field Documentation 🔥

💜 struct rte_rcu_qsbr* v

this is the RCU QSBR variable, bestie. the actual variable. the main character of the RCU situation. ✨

Definition at line 118 of file rte_fib.h.

🧚 enum rte_fib_qsbr_mode mode

the mode of RCU QSBR, iykyk. go check out RTE_FIB_QSBR_MODE_xxx for the full menu of options.

Default: RTE_FIB_QSBR_MODE_DQ, which creates a defer queue for reclaim. so if you don't touch it, that's what you're getting. slay. 🎀

Definition at line 122 of file rte_fib.h.

🍓 uint32_t dq_size

the RCU defer queue size. that's it, that's the field.

Default: RTE_FIB_RCU_DQ_RECLAIM_SZ.

Definition at line 126 of file rte_fib.h.

👑 uint32_t reclaim_thd

the threshold to trigger auto reclaim. hit the threshold and the auto reclaim kicks in, no cap. 💅

Definition at line 128 of file rte_fib.h.

⭐ uint32_t reclaim_max

the max entries to reclaim in one go. okay so it's not gonna do infinite reclaim in a single pass, there's a cap and this is it.

Default: RTE_FIB_RCU_DQ_RECLAIM_MAX.

Definition at line 132 of file rte_fib.h.

and that's the whole page bestie!! this was DPDK Version 25.11.3, page rte_fib_rcu_config(3), and yes the header line was up there at the top too. go configure your FIB, drink some water, and remember: the defaults are your friends (RTE_FIB_QSBR_MODE_DQ, RTE_FIB_RCU_DQ_RECLAIM_SZ, RTE_FIB_RCU_DQ_RECLAIM_MAX) until proven otherwise. mwah 💖✨
