igb_io_resume(9)

okay so bestie, this is igb_io_resume(9) from the Kernel API Manual, and it's literally the “traffic can start flowing again” callback. no cap, it's giving tiny-but-important main character energy. 💅✨

💖 NAME 💖

igb_io_resume — called when traffic can start flowing again. That's the whole vibe: it's the callback that signals the comeback era. 🎀

✨ SYNOPSIS ✨

void igb_io_resume (struct pci_dev *pdev );

🫶 ARGUMENTS 🫶

• pdev — pointer to the PCI device, fr fr. That's the one thing it takes. 🫶

🌸 DESCRIPTION 🌸

okay so here's the tea: this callback gets called when the error recovery driver tells us that it's OK to resume normal operation. 🦋

The implementation resembles the second-half of the __igb_resume routine. iykyk. That's literally the description — no extra lore, no invented side quests. 💜
