STRUCT IWL_PHY_SPECIFIC_CFG(9)

💖 NAME 💖

okay so welcome to the struct iwl_phy_specific_cfg(9) page in the Kernel API Manual, bestie 🫶 — this one is all about specific PHY filter configuration. Lowkey tiny struct, highkey important ✨.

✨ SYNOPSIS ✨

struct iwl_phy_specific_cfg {
    __le32 filter_cfg_chains[4];
};

🎀 Members 🎀

• filter_cfg_chains — this is the filter config id for LMAC1 chain A, LMAC1 chain B, LMAC2 chain A, LMAC2 chain B (in that order) 💅 yes, that exact order, no cap. The values are: 0 means no filter; 0xffffffff is reserved; otherwise it’s a filter id 🔥.

🦋 Description 🦋

So this struct gets sent as part of the phy configuration command (v3) to configure specific FW defined PHY filters that can be applied to each antenna 🌸. That’s the whole vibe: FW defined PHY filters, applied per antenna, and the struct is just out here doing its little config moment 🎀.
