ENUM IONIC_PORT_LOOPBACK_MODE(9)

💖 NAME 💖

okay so bestie, let me put you onto enum ionic_port_loopback_mode(9) — this is from the Kernel API Manual, and it's literally the enum that tells you which loopback modes exist for the ionic driver. it's giving "short but iconic" energy, no cap. 🎀

🌈 SYNOPSIS 🌈

enum ionic_port_loopback_mode {
    IONIC_PORT_LOOPBACK_MODE_NONE ,
    IONIC_PORT_LOOPBACK_MODE_MAC ,
    IONIC_PORT_LOOPBACK_MODE_PHY

};

💅 CONSTANTS 💅

• IONIC_PORT_LOOPBACK_MODE_NONE — bestie, this one just disables loopback entirely. no loopback, no drama. 💀
• IONIC_PORT_LOOPBACK_MODE_MAC — this is the MAC loopback vibe. slay. ✨
• IONIC_PORT_LOOPBACK_MODE_PHY — and this one? PHY/SerDes loopback, for when you wanna get all up in the physical layer. 🔥

okay so this page is lowkey connected to the entire ionic universe, and you know I had to list every single one. the kernel file is ./drivers/net/ethernet/pensando/ionic/ionic_if.h and then there's this whole friend group of structs and enums — fr fr, they're all here:
