STRUCT ICE_ETH56G_MAC_REG_CFG(9)

💖 NAME 💖

struct ice_eth56g_mac_reg_cfg — the MAC config values for specific PTP registers, bestie 💅 (this is from the Kernel API Manual, and yes, it slays)

✨ SYNOPSIS ✨

okay so here's the whole struct, no cap:

struct ice_eth56g_mac_reg_cfg {
    struct {
      u8 def;
      u8 rs;
    } tx_mode;
    u8 tx_mk_dly;
    struct {
      u8 def;
      u8 onestep;
    } tx_cw_dly;
    struct {
      u8 def;
      u8 rs;
    } rx_mode;
    struct {
      u8 def;
      u8 rs;
    } rx_mk_dly;
    struct {
      u8 def;
      u8 rs;
    } rx_cw_dly;
    u8 blks_per_clk;
    u16 blktime;
    u16 mktime;
    struct {
      u32 serdes;
      u32 no_fec;
      u32 fc;
      u32 rs;
      u32 sfd;
      u32 onestep;
    } tx_offset;
    struct {
      u32 serdes;
      u32 no_fec;
      u32 fc;
      u32 rs;
      u32 sfd;
      u32 bs_ds;
    } rx_offset;
 };

🎀 MEMBERS 🎀

• tx_mode — the Tx timestamp compensation mode, periodt ✨
• tx_mk_dly — Tx timestamp marker start strobe delay 🕐
• tx_cw_dly — Tx timestamp codeword start strobe delay 🕐
• rx_mode — the Rx timestamp compensation mode 💫
• rx_mk_dly — Rx timestamp marker start strobe delay 🕐
• rx_cw_dly — Rx timestamp codeword start strobe delay 🕐
• blks_per_clk — the number of blocks transferred per clock cycle 🔥
• blktime — block time, fixed point 🧮
• mktime — marker time, fixed point 🧮
• tx_offset — total Tx offset, fixed point 🎯
• rx_offset — total Rx offset, contains value for bitslip/deskew, fixed point 🎯

🦋 DESCRIPTION 🦋

okay so here's the tea on the numerics ☕ — all the fixed point registers except Rx offset are 23 bit unsigned ints with a 9 bit fractional. and Rx offset? she's different 💅 — she's an 11 bit unsigned int with a 9 bit fractional. iykyk 🫶
