i40e_get_pba_string(9)
π i40e_get_pba_string(9) β from the Kernel API Manual, bestie β¨
Okay so this is a page straight out of the Kernel API Manual, and it's about the little function that goes digging in your NIC's EEPROM to find out what part number it is. Cute, right? Let's get into it π«Ά
πΈ NAME πΈ
i40e_get_pba_string β reads the part number string from the EEPROM πΎβ¨
π SYNOPSIS π
void i40e_get_pba_string (struct i40e_hw *hw );
That's it. Void return. No drama. No cap. π
π¦ ARGUMENTS π¦
hwβ a pointer to the hardware structure, aka your ticket to the actual silicon. Hand it over and the function knows where to look π
β¨ DESCRIPTION β¨
So here's the vibe: this function reads the part number string out of the EEPROM, stores it into a newly allocated buffer, and then saves the resulting pointer into the i40e_hw->pba_id field. π
Like, the function handles the memory allocation for you and just leaves the pointer sitting pretty in pba_id, so you can go read your NIC's part number whenever you feel like it. It's giving responsible adult energy honestly π
Quick note bestie: the buffer is newly allocated by this function β the description says the pointer lands in i40e_hw->pba_id, and that's literally all the page tells us. Don't come for me with follow-up questions I can't answer from the source material π
π SEE ALSO π
Okay this is the part where the manpage goes full main-character and lists everyone in the friend group π β same kernel file, and a truly iconic number of related functions. Buckle up, we're going through the whole roster:
