ice_tcam_write_entry(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 NAME 🌸

Okay so welcome to ice_tcam_write_entry(9) in the Kernel API Manual, bestie 💖. This function does one iconic thing: write TCAM entry. That's the whole name, no cap, and yes it's giving very specific kernel-energy.

✨ SYNOPSIS ✨

The signature is literally right here, every token present and accounted for:

int ice_tcam_write_entry (struct ice_hw *hw , enum ice_block blk , u16 idx , u8 prof_id , u8 ptg , u16 vsig , u8 cdid , u16 flags , u8 vl_msk[ICE_TCAM_KEY_VAL_SZ] , u8 dc_msk[ICE_TCAM_KEY_VAL_SZ] , u8 nm_msk[ICE_TCAM_KEY_VAL_SZ] );

🎀 ARGUMENTS 🎀

Here is the whole cast, and we are not skipping a single one 💅:

  • hw — pointer to the HW struct
  • blk — the block in which to write profile ID to
  • idx — the entry index to write to
  • prof_id — profile ID
  • ptg — packet type group (PTG) portion of key
  • vsig — VSIG portion of key
  • cdid — CDID portion of key
  • flags — flag portion of key
  • vl_msk — valid mask
  • dc_msk — don't care mask
  • nm_msk — never match mask
