ixgbe_get_pfa_module_tlv(9)

📦 version 7.3.1, in nixpkgs unstable

💖 ixgbe_get_pfa_module_tlv — your fave little TLV hunter 💖

okay so bestie, this is a kernel API manual page for ixgbe_get_pfa_module_tlv(9) and it's literally about digging through NVM PFA to find a sub module TLV. no cap, it's giving "detective but make it firmware." 🕵️‍♀️✨

🌸 SYNOPSIS 🌸

int ixgbe_get_pfa_module_tlv (struct ixgbe_hw *hw , u16 *module_tlv ,
u16 *module_tlv_len , u16 module_type );

🎀 ARGUMENTS 🎀

  • hw — pointer to hardware structure (the main character struct, fr fr)
  • module_tlv — pointer to module TLV to return (where the TLV pointer goes 👀)
  • module_tlv_len — pointer to module TLV length to return (yes, the length also comes back here)
  • module_type — module type requested (what you're looking for)

✨ DESCRIPTION ✨

So basically this function finds the requested sub module TLV type from the Preserved Field Area (PFA) and returns the TLV pointer and length. the way that works is: you ask for a module_type, it goes hunting in the PFA, and hands you back module_tlv and module_tlv_len so you can then read the variable length TLV value yourself. caller does the reading, this function just does the finding. slay. 💅

🦋 RETURN 🦋

it returns the exit code of the operation. that's it, that's the tea. 🍵

okay and finally the lil sign-off: this is from ./drivers/net/ethernet/intel/i... (the kernel source, you know the vibes), dated October 2026, and the page itself is ixgbe_get_pfa_module_tlv(9). that's the whole manual, bestie — go read some TLVs, you got this 🫶💜🌈
