DPNI_OPT_HAS_POLICING(9)

💖 DPNI_OPT_HAS_POLICING(9) 💖

okay so bestie, welcome to the Kernel API Manual entry for DPNI_OPT_HAS_POLICING(9) — yes the manual name is literally in the title, we're fancy like that ✨

---

🎀 NAME 🎀

DPNI_OPT_HAS_POLICING — the flag that says "allocate policers for this DPNI" 💅

And like, what are those policers for? They can be used to rate-limit traffic per traffic class (TC) basis. That's the whole vibe. Traffic shaping but make it per-TC, no cap 🚦

✨ SYNOPSIS ✨

DPNI_OPT_HAS_POLICING

that's it. that's the synopsis. she's short, she's iconic, she doesn't need a synopsis essay 🫶

🦋 SEE ALSO 🦋

okay so this is where it gets real — the related-reading list is genuinely enormous and I'm obsessed. First up, the actual kernel file this lives in:

• Kernel file ./drivers/net/ethernet/freescale/dpaa2/dpni.h

then the flag besties:

• DPNI_MAX_TC(9), DPNI_MAX_DPBP(9), DPNI_ALL_TCS(9), DPNI_ALL_TC_FLOWS(9), DPNI_NEW_FLOW_ID(9), DPNI_OPT_TX_FRM_RELEASE(9), DPNI_OPT_NO_MAC_FILTER(9), DPNI_OPT_SHARED_CONGESTION(9), DPNI_OPT_HAS_KEY_MASKING(9), DPNI_OPT_NO_FS(9), DPNI_OPT_SHARED_FS(9)

the pool / attr era:

• struct dpni_pools_cfg(9), struct dpni_attr(9)

error-code girlies (we love a good error enum):

• DPNI_ERROR_EOFHE(9), DPNI_ERROR_FLE(9), DPNI_ERROR_FPE(9), DPNI_ERROR_PHE(9), DPNI_ERROR_L3CE(9), DPNI_ERROR_L4CE(9), enum dpni_error_action(9), struct dpni_error_cfg(9)

buffer layout squad — truly the main characters of "where do my bytes go":

• DPNI_BUF_LAYOUT_OPT_TIMESTAMP(9), DPNI_BUF_LAYOUT_OPT_PARSER_RESULT(9), DPNI_BUF_LAYOUT_OPT_FRAME_STATUS(9), DPNI_BUF_LAYOUT_OPT_PRIVATE_DATA_SIZE(9), DPNI_BUF_LAYOUT_OPT_DATA_ALIGN(9), DPNI_BUF_LAYOUT_OPT_DATA_HEAD_ROOM(9), DPNI_BUF_LAYOUT_OPT_DATA_TAIL_ROOM(9), struct dpni_buffer_layout(9)

queues, stats, links, distribution:

• enum dpni_queue_type(9), enum dpni_offload(9), union dpni_statistics(9), struct dpni_link_cfg(9), struct dpni_link_state(9), enum dpni_dist_mode(9), enum dpni_fs_miss_action(9), struct dpni_fs_tbl_cfg(9), struct dpni_rx_tc_dist_cfg(9), DPNI_FS_MISS_DROP(9), struct dpni_rx_dist_cfg(9), struct dpni_qos_tbl_cfg(9)

destinations & queues, part two:

• enum dpni_dest(9), struct dpni_queue(9), struct dpni_queue_id(9)

congestion notification (the rate-limit-adjacent lore 👀):

• enum dpni_congestion_unit(9), enum dpni_congestion_point(9), struct dpni_dest_cfg(9), DPNI_CONG_OPT_FLOW_CONTROL(9), struct dpni_congestion_notification_cfg(9), struct dpni_taildrop(9)

rules & flow steering:

• struct dpni_rule_cfg(9), DPNI_FS_OPT_DISCARD(9), DPNI_FS_OPT_SET_FLC(9), DPNI_FS_OPT_SET_STASH_CONTROL(9), struct dpni_fs_action_cfg(9)

and the final two absolute icons:

• struct dpni_tx_shaping_cfg(9), struct dpni_single_step_cfg(9)

bestie that's 58 references, I counted, and every single one is here. go read them. or don't. but like, they're there 💀
