ice_init_supported_rxdids(9)

📦 version 7.3.1, in nixpkgs unstable

NAME 💖

okay so bestie, welcome to the ice_init_supported_rxdids(9) page from the Kernel API Manual — we're doing Intel ice driver lore today and it's honestly giving main character energy. ✨

ice_init_supported_rxdids — Initialize supported Rx descriptor IDs.

SYNOPSIS 🎀

void ice_init_supported_rxdids (struct ice_hw *hw , struct ice_pf *pf );

ARGUMENTS 🦋

  • hw — pointer to the hardware structure
  • pf — pointer to pf structure

DESCRIPTION 🌸

okay so the pf->supported_rxdids bitmap is literally the vibe-check list that tells VFs which descriptor formats the PF hardware supports. 💅 The exact list of supported RXDIDs depends on the loaded DDP package — no cap, the DDP package is the main character here.

You can figure out the IDs by reading the GLFLXP_RXDID_FLAGS register after the DDP package is loaded. 🫶

big note, bestie: the legacy 32-byte RXDID 0 is always supported, but it is not listed in the DDP package. And the 16-byte legacy descriptor is never supported by VFs — periodt, never, not even a little. 😭
