| 50 | * The AX88172 provides USB ethernet supports at 10 and 100Mbps. |
| 51 | * It uses an external PHY (reference designs use a RealTek chip), |
| 52 | * and has a 64-bit multicast hash filter. There is some information |
| 53 | * missing from the manual which one needs to know in order to make |
| 54 | * the chip function: |
| 55 | * |
| 56 | * - You must set bit 7 in the RX control register, otherwise the |
| 57 | * chip won't receive any packets. |
| 58 | * - You must initialize all 3 IPG registers, or you won't be able |
| 59 | * to send any packets. |
| 60 | * |
| 61 | * Note that this device appears to only support loading the station |
| 62 | * address via autload from the EEPROM (i.e. there's no way to manaully |
| 63 | * set it). |
| 64 | * |
| 65 | * (Adam Weinberger wanted me to name this driver if_gir.c.) |
