igc_check_reset_block(9)

💅 igc_check_reset_block 💅

okay so real talk, this is a kernel API manual page for igc_check_reset_block — that's the function name, and it lives in section 9 of the manual, bestie. buckle up, it's actually a short one 🎀

---

✨ NAME ✨

igc_check_reset_block — checks if the PHY reset is blocked, no cap 👀

---

🌸 SYNOPSIS 🌸

s32 igc_check_reset_block (struct igc_hw *hw );

literally that's the whole signature. she's cute, she's concise, she returns an s32 🫶

---

🦋 ARGUMENTS 🦋

• hw — pointer to the HW structure 💖 that's it. that's the only argument. she takes one (1) struct pointer and she's thriving.

ngl if you're passing something that isn't a pointer to the HW structure, that's on you bestie, the manual is not responsible 🙈

---

🔥 DESCRIPTION 🔥

okay so what does she actually do? she reads the PHY management control register and checks whether a PHY reset is blocked. that's the whole vibe check 😌

then she reports back:

• if a reset is not blocked → she returns 0 (the good ending ✨)
• otherwise → she returns IGC_ERR_BLK_PHY_RESET (12) (the "bestie the reset is blocked" ending 💀)

that's it. no hidden lore. no extra parameters. she's an icon, she's a one-trick pony, and honestly? the trick ate 🔥
