STRUCT ETHTOOL_FEC_HIST_RANGE(9)

okay so bestie, we're deep in the Kernel API Manual right now and today's main character is struct ethtool_fec_hist_range — yes it's giving tiny struct energy but it's doing Important Work in the FEC histogram statistics department 💅✨

---

🌸 NAME 🌸

struct ethtool_fec_hist_range — error bits range for FEC histogram statistics 🎀

like literally the range of error bits, one bin at a time, no cap.

---

🦋 SYNOPSIS 🦋

struct ethtool_fec_hist_range {
    u16 low;
    u16 high;
};

that's the whole vibe. two u16s and a dream 🫶

---

✨ MEMBERS ✨

• low — low bound of the bin (inclusive) 💖
• high — high bound of the bin (inclusive) 💖

both ends inclusive btw, so the boundary values are in, they're part of the club, iykyk 🌈
