💖 ice_vc_fdir_is_raw_flow — check if FDIR flow is raw (binary) 💖

Hey bestie! Welcome to the ice_vc_fdir_is_raw_flow(9) page in the Kernel API Manual — yes, the manual name is folded in right near the top like a cute little bookmark. 🎀

💅 NAME 💅

ice_vc_fdir_is_raw_flow — check if FDIR flow is raw (binary)

✨ SYNOPSIS ✨

bool ice_vc_fdir_is_raw_flow (struct virtchnl_proto_hdrs *proto );

🫶 ARGUMENTS 🫶

  • proto — virtchnl protocol headers. That’s the thing we’re checking, bestie. 💖

🌸 DESCRIPTION 🌸

Okay so this function is doing a little vibe check on an FDIR rule: is it a raw flow (protocol agnostic flow), or not? 🧚✨

Tea time, important note: a common FDIR rule must have non-zero proto->count. So we use the tunnel_level and the count of proto as the indicators. If both tunnel_level and count of proto are zero, this FDIR rule will be regarded as raw flow. No cap. 💅

🎀 RETURN 🎀

true if headers describe raw flow, false otherwise. Simple as that, bestie. 🫶
