MDIO_AN_T1_ADV_M_MST is T4 of Link codeword Base Page. The spec says: "Transmitted Nonce Field (T[4:0]) is a 5-bit wide field whose lower 4 bits contains a random or pseudorandom number. A new value shall be generated for each entry to the Ability Detect state" Should we actually do it? > +/* BASE-T1 auto-negotiation advertisement register [47:32] */ > +#define MDIO_AN_T1_ADV_H_10L_TX_HI_REQ 0x1000 /* 10BASE-T1L High Level Transmit Request */ > +#define MDIO_AN_T1_ADV_H_10L_TX_HI 0x2000 /* 10BASE-T1L High Level Transmit Ability */ > + > +/* BASE-T1 AN LP's base page register [15:0] */ > +#define MDIO_AN_T1_LP_L_PAUSE_CAP LPA_PAUSE_CAP > +#define MDIO_AN_T1_LP_L_PAUSE_ASYM LPA_PAUSE_ASYM > +#define MDIO_AN_T1_LP_L_FORCE_MS 0x1000 /* LP Force Master/slave Configuration */ > +#define MDIO_AN_T1_LP_L_REMOTE_FAULT LPA_RFAULT > +#define MDIO_AN_T1_LP_L_ACK LPA_LPACK > +#define MDIO_AN_T1_LP_L_NEXT_PAGE_REQ LPA_NPAGE > + > +/* BASE-T1 AN LP's base page register [31:16] */ > +#define MDIO_AN_T1_LP_M_MST 0x0080 /* LP master preference */ 0x0080 is A2 == 1000BASE-T1 ability.
