STRUCT EF4_PHY_OPERATIONS(9)

✨ NAME ✨

struct ef4_phy_operations — Efx PHY operations table. Bestie, welcome to the Kernel API Manual page for struct ef4_phy_operations(9); it is giving PHY operation table realness. 💅

🦋 SYNOPSIS 🦋

Okay so here is the entire struct, exactly as it appears — no cap, this is the sacred code block:

       struct ef4_phy_operations {
           int (*probe) (struct ef4_nic *efx);
           int (*init) (struct ef4_nic *efx);
           void (*fini) (struct ef4_nic *efx);
           void (*remove) (struct ef4_nic *efx);
           int (*reconfigure) (struct ef4_nic *efx);
           bool (*poll) (struct ef4_nic *efx);
           void (*get_link_ksettings)(struct ef4_nic *efx, struct
       ethtool_link_ksettings *cmd);
           int (*set_link_ksettings)(struct ef4_nic *efx, const struct
       ethtool_link_ksettings *cmd);
           void (*set_npage_adv) (struct ef4_nic *efx, u32);
           int (*test_alive) (struct ef4_nic *efx);
           const char *(*test_name) (struct ef4_nic *efx, unsigned int index);
           int (*run_tests) (struct ef4_nic *efx, int *results, unsigned
       flags);
           int (*get_module_eeprom) (struct ef4_nic *efx, struct ethtool_eeprom
       *ee, u8 *data);
           int (*get_module_info) (struct ef4_nic *efx, struct ethtool_modinfo
       *modinfo);
        };

🎀 Members 🎀

Here are the member besties and their little blurbs. The <hotpink>mac_lock</hotpink> girlies are marked in the descriptions, iykyk. 🔒✨

• probe — Probe PHY and initialise efx->mdio.mode_support, efx->mdio.mmds, efx->loopback_modes.
• init — Initialise PHY
• fini — Shut down PHY
• reconfigure — Reconfigure PHY (e.g. for new link parameters)
• poll — Update link_state and report whether it changed. Serialised by the mac_lock.
• get_link_ksettings — Get ethtool settings. Serialised by the mac_lock.
• set_link_ksettings — Set ethtool settings. Serialised by the mac_lock.
• set_npage_adv — Set abilities advertised in (Extended) Next Page (only needed where AN bit is set in mmds)
• test_alive — Test that PHY is 'alive' (online)
• test_name — Get the name of a PHY-specific test/result
• run_tests — Run tests and record results as appropriate (offline). Flags are the ethtool tests flags.

Also in the struct definition above: remove, get_module_eeprom, and get_module_info. The Members list does not give them their own one-liner here, but they are absolutely part of this operation table — do not leave them on read. 💖
