STRUCT PHYLINK_MAC_OPS(9)

✨ struct phylink_mac_ops(9) — a Kernel API Manual moment ✨

okay bestie, so this is a page from the Kernel API Manual, and it's all about a lil struct called struct phylink_mac_ops — literally the MAC operations structure, and it's giving very main-character energy in the phylink world 🎀

🌸 NAME 🌸

struct phylink_mac_ops — the MAC operations structure. that's it, that's the name, no cap 💅

🦋 SYNOPSIS 🦋

here's the whole vibe, verbatim, don't @ me:

struct phylink_mac_ops {
    unsigned long (*mac_get_caps)(struct phylink_config *config,
phy_interface_t interface);
    struct phylink_pcs *(*mac_select_pcs)(struct phylink_config *config,
phy_interface_t interface);
    int (*mac_prepare)(struct phylink_config *config, unsigned int mode,
phy_interface_t iface);
    void (*mac_config)(struct phylink_config *config, unsigned int mode,
const struct phylink_link_state *state);
    int (*mac_finish)(struct phylink_config *config, unsigned int mode,
phy_interface_t iface);
    void (*mac_link_down)(struct phylink_config *config, unsigned int
mode, phy_interface_t interface);
    void (*mac_link_up)(struct phylink_config *config, struct phy_device
*phy, unsigned int mode, phy_interface_t interface, int speed, int
duplex, bool tx_pause, bool rx_pause);
    void (*mac_disable_tx_lpi)(struct phylink_config *config);
    int (*mac_enable_tx_lpi)(struct phylink_config *config, u32 timer,
bool tx_clk_stop);
    int (*mac_wol_set)(struct phylink_config *config, u32 wolopts, const
u8 *sopass);
 };

👑 MEMBERS 👑

these are the function pointers, aka the whole squad 🫶

• mac_get_caps — get the MAC capabilities for the interface mode. it's literally just asking "what can u do, babe?" 💪
• mac_select_pcs — pick a PCS for the interface mode. choosing your fave, iconic behavior ✨
• mac_prepare — prep for a major reconfiguration of the interface. big glow-up incoming, get ready 🌈
• mac_config — configure the MAC for the selected mode and state. the actual makeover moment 💅
• mac_finish — wrap up that major reconfiguration of the interface. the finale, periodt 🎀
• mac_link_down — take the link down. sad girl hours, but someone has to do it 😭
• mac_link_up — let the link come up. yasss, we're so back 🔥
• mac_disable_tx_lpi — disable LPI. bye bestie 👋
• mac_enable_tx_lpi — enable and configure LPI. multitasking queen 👑
• mac_wol_set — configure Wake-on-Lan settings at the MAC. the MAC wakes up like it's got a 6am alarm ⭐
