i40e_info_eetrack(9)

💅 i40e_info_eetrack(9) — like, the EETrackID string formatter, bestie

okay so real talk, this is a page from the Kernel API Manual (section 9, driver-land, iykyk) and it's literally just one little function that formats a string. tiny icon. but she does her job perfectly and we're gonna respect her 💖

✨ NAME ✨

i40e_info_eetrack — format the EETrackID string

like, she takes the EETrackID and turns it into a pretty string. that's the whole vibe. no cap.

---

🦋 SYNOPSIS 🦋

void i40e_info_eetrack (struct i40e_hw *hw , char *buf , size_t len );

returns nothing (void, queen of giving zero back but still slaying), takes three things. periodt.

---

🎀 ARGUMENTS 🎀

• hw — ptr to the hardware info 💅 like, hand her the hardware info struct and she'll do the rest
• buf — string buffer to store 🌸 this is where the formatted string goes, no thoughts just vibes
• len — buffer size ✨ important!! she needs to know how much room she's got

---

💜 DESCRIPTION 💜

Returns hexadecimally formated EETrackID if it is different from I40E_OEM_EETRACK_ID or empty string.

so basically: if the EETrackID is not I40E_OEM_EETRACK_ID, you get it back all formatted in hex, gorgeous, iconic 🔥. but if it is I40E_OEM_EETRACK_ID? you get an empty string. nothing. silence. she simply doesn't vibe with that value and honestly? respect 🙈

ngl the conditional is doing a lot of heavy lifting here — different from I40E_OEM_EETRACK_ID = hex string, otherwise = empty string. don't forget it, bestie, it's literally the whole function 😭
