| #define NIC_PHY_ADDR 0 |
PHY address.
Any other than 0 seems to create problems with Atmel's evaluation kits.
Definition at line 186 of file at91_emac.c.
| #define NIC_PHY_UID 0xffffffff |
PHY ID.
If set to 0xffffffff, the PHY id will be ignored.
Definition at line 195 of file at91_emac.c.
| #define CHECK_ALL_KNOWN_PHY_IDS |
Check all known PHY IDs.
If defined, perform the old PHY checks. This ensures compatibility at the cost of bloat. Should be removed later on when all boards have their PHY ids in their configuration.
