i40e_dcb_hw_...e_pool_sizes(9)

✨ NAME ✨

okay so welcome to the Kernel API Manual, bestie — this is the page for i40e_dcb_hw_calculate_pool_sizes, and her whole job is to configure dcb pool sizes. 💅

✨ SYNOPSIS ✨

void i40e_dcb_hw_calculate_pool_sizes (struct i40e_hw *hw , u8 num_ports
       , bool eee_enabled , u8 pfc_en , u32 *mfs_tc , struct i40e_rx_pb_config
       *pb_cfg );

💖 ARGUMENTS 💖

• hw — pointer to the hw struct. That's the hardware struct, the main character energy of this call.
• num_ports — Number of available ports on the device. Like, how many ports are we even working with?
• eee_enabled — EEE enabled for the given port. Is EEE on for this port? This bool is the vibe check.
• pfc_en — Bit map of PFC enabled traffic classes. A whole bitmap of which traffic classes have PFC enabled.
• mfs_tc — Array of max frame size for each traffic class. One max frame size per traffic class, sitting in an array.
• pb_cfg — pointer to packet buffer configuration. Literally a pointer to the packet buffer config. Periodt.

🔥 DESCRIPTION 🔥

okay so the actual tea: i40e_dcb_hw_calculate_pool_sizes calculates the shared and dedicated per TC pool sizes, the watermarks, and the threshold values. That's it, that's the whole description — she's doing the DCB pool-size math, no cap. 🧚
