ASIX conveniently doesn't document the 'set 42 * NODEID' command in their datasheet (thanks a lot guys). 43 * To make handling these commands easier, I added some extra data which is 44 * decided by the axe_cmd() routine. Commands are encoded in 16 bits, with 45 * the format: LDCC. L and D are both nibbles in the high byte. L represents 46 * the data length (0 to 15) and D represents the direction (0 for vendor read, 47 * 1 for vendor write). CC is the command byte, as specified in the manual. 48 */ 49 50#define AXE_CMD_IS_WRITE(x) (((x) & 0x0F00) >> 8) 51#define AXE_CMD_LEN(x) (((x) & 0xF000) >> 12) 52#define AXE_CMD_CMD(x) ((x) & 0x00FF) 53 54#define AXE_172_CMD_READ_RXTX_SRAM 0x2002 55#define AXE_182_CMD_READ_RXTX_SRAM 0x8002 56#define AXE_172_CMD_WRITE_RX_SRAM 0x0103 57#define AXE_182_CMD_WRITE_RXTX_SRAM 0x8103 58#define AXE_172_CMD_WRITE_TX_SRAM 0x0104 59#define AXE_CMD_MII_OPMODE_SW 0x0106 60#define AXE_CMD_MII_READ_REG 0x2007 61#define AXE_CMD_MII_WRITE_REG 0x2108 62#define AXE_CMD_MII_READ_OPMODE 0x1009 63#define AXE_CMD_MII_OPMODE_HW 0x010A 64#define AXE_CMD_SROM_READ 0x200B 65#define AXE_CMD_SROM_WRITE 0x010C 66#define AXE_CMD_SROM_WR_ENABLE 0x010D 67#define AXE_CMD_SROM_WR_DISABLE 0x010E 68#define AXE_CMD_RXCTL_READ 0x200F 69#define AXE_CMD_RXCTL_WRITE 0x0110 70#define AXE_CMD_READ_IPG012 0x3011 71#define AXE_172_CMD_WRITE_IPG0 0x0112 72#define AXE_178_CMD_WRITE_IPG012 0x0112 73#define AXE_172_CMD_WRITE_IPG1 0x0113 74#define AXE_178_CMD_READ_NODEID 0x6013 75#define AXE_172_CMD_WRITE_IPG2 0x0114 76#define AXE_178_CMD_WRITE_NODEID 0x6114 77#define AXE_CMD_READ_MCAST 0x8015 78#define AXE_CMD_WRITE_MCAST 0x8116 79#define AXE_172_CMD_READ_NODEID 0x6017 80#define AXE_172_CMD_WRITE_NODEID 0x6118 81 82#define AXE_CMD_READ_PHYID 0x2019 83#define AXE_172_CMD_READ_MEDIA 0x101A 84#define AXE_178_CMD_READ_MEDIA 0x201A 85#define AXE_CMD_WRITE_MEDIA 0x011B 86#define AXE_CMD_READ_MONITOR_MODE 0x101C 87#define AXE_CMD_WRITE_MONITOR_MODE 0x011D 88#define AXE_CMD_READ_GPIO 0x101E 89#define AXE_CMD_WRITE_GPIO 0x011F 90 91#define AXE_CMD_SW_RESET_REG 0x0120 92#define AXE_CMD_SW_PHY_STATUS 0x0021 93#define AXE_CMD_SW_PHY_SELECT 0x0122 94 95#define AXE_SW_RESET_CLEAR 0x00 96#define AXE_SW_RESET_RR 0x01 97#define AXE_SW_RESET_RT 0x02 98#define AXE_SW_RESET_PRTE 0x04 99#define AXE_SW_RESET_PRL 0x08 100#define AXE_SW_RESET_BZ 0x10 101#define AXE_SW_RESET_IPRL 0x20 102#define AXE_SW_RESET_IPPD 0x40 103 104/* AX88178 documentation says to always write this bit... */ 105#define AXE_178_RESET_MAGIC 0x40 106 107#define AXE_178_MEDIA_GMII 0x0001 108#define AXE_MEDIA_FULL_DUPLEX 0x0002 109#define AXE_172_MEDIA_TX_ABORT_ALLOW 0x0004 110 111/* AX88178/88772 documentation says to always write 1 to bit 2 */ 112#define AXE_178_MEDIA_MAGIC 0x0004 113/* AX88772 documentation says to always write 0 to bit 3 */ 114#define AXE_178_MEDIA_ENCK 0x0008 115#define AXE_172_MEDIA_FLOW_CONTROL_EN 0x0010 116#define AXE_178_MEDIA_RXFLOW_CONTROL_EN 0x0010 117#define AXE_178_MEDIA_TXFLOW_CONTROL_EN 0x0020 118#define AXE_178_MEDIA_JUMBO_EN 0x0040 119#define AXE_178_MEDIA_LTPF_ONLY 0x0080 120#define AXE_178_MEDIA_RX_EN 0x0100 121#define AXE_178_MEDIA_100TX 0x0200 122#define AXE_178_MEDIA_SBP 0x0800 123#define AXE_178_MEDIA_SUPERMAC 0x1000 124 125#define AXE_RXCMD_PROMISC 0x0001 126#define AXE_RXCMD_ALLMULTI 0x0002 127#define AXE_172_RXCMD_UNICAST 0x0004 128#define AXE_178_RXCMD_KEEP_INVALID_CRC 0x0004 129#define AXE_RXCMD_BROADCAST 0x0008 130#define AXE_RXCMD_MULTICAST 0x0010 131#define AXE_RXCMD_ENABLE 0x0080 132#define AXE_178_RXCMD_MFB_MASK 0x0300 133#define AXE_178_RXCMD_MFB_2048 0x0000 134#define AXE_178_RXCMD_MFB_4096 0x0100 135#define AXE_178_RXCMD_MFB_8192 0x0200 136#define AXE_178_RXCMD_MFB_16384 0x0300 137 138#define AXE_PHY_SEL_PRI 1 139#define AXE_PHY_SEL_SEC 0 140#define AXE_PHY_TYPE_MASK 0xE0 141#define AXE_PHY_TYPE_SHIFT 5 142#define AXE_PHY_TYPE(x) \ 143 (((x) & AXE_PHY_TYPE_MASK) >> AXE_PHY_TYPE_SHIFT) 144 145#define PHY_TYPE_100_HOME 0 /* 10/100 or 1M HOME PHY */ 146#define PHY_TYPE_GIG 1 /* Gigabit PHY */ 147#define PHY_TYPE_SPECIAL 4 /* Special case */ 148#define PHY_TYPE_RSVD 5 /* Reserved */ 149#define PHY_TYPE_NON_SUP 7 /* Non-supported PHY */ 150 151#define AXE_PHY_NO_MASK 0x1F 152#define AXE_PHY_NO(x) ((x) & AXE_PHY_NO_MASK) 153 154#define AXE_772_PHY_NO_EPHY 0x10 /* Embedded 10/100 PHY of AX88772 */ 155 156#define AXE_BULK_BUF_SIZE 16384 /* bytes */ 157 158#define AXE_CTL_READ 0x01 159#define AXE_CTL_WRITE 0x02 160 161#define AXE_CONFIG_IDX 0 /* config number 1 */ 162#define AXE_IFACE_IDX 0 163 164struct axe_sframe_hdr { 165 uint16_t len; 166 uint16_t ilen; 167} __packed; 168 169#define GET_MII(sc) usb2_ether_getmii(&(sc)->sc_ue) 170 171/* The interrupt endpoint is currently unused by the ASIX part. */ 172enum { 173 AXE_BULK_DT_WR, 174 AXE_BULK_DT_RD, 175 AXE_INTR_DT_RD, 176 AXE_N_TRANSFER, 177}; 178 179struct axe_softc { 180 struct usb2_ether sc_ue; 181 struct mtx sc_mtx; 182 struct usb2_xfer *sc_xfer[AXE_N_TRANSFER]; 183 int sc_phyno; 184 185 int sc_flags; 186#define AXE_FLAG_LINK 0x0001 187#define AXE_FLAG_772 0x1000 /* AX88772 */ 188#define AXE_FLAG_178 0x2000 /* AX88178 */ 189 190 uint8_t sc_ipgs[3]; 191 uint8_t sc_phyaddrs[2]; 192}; 193 194#define AXE_LOCK(_sc) mtx_lock(&(_sc)->sc_mtx) 195#define AXE_UNLOCK(_sc) mtx_unlock(&(_sc)->sc_mtx) 196#define AXE_LOCK_ASSERT(_sc, t) mtx_assert(&(_sc)->sc_mtx, t) 197
