| 7 | + Must be defined if CONFIG_FEC_MXC is defined. | |
| 8 | + | |
| 9 | +CONFIG_FEC_XCV_TYPE | |
| 10 | + Defaults to MII100 for 100 Base-tx. | |
| 11 | + RGMII selects 1000 Base-tx reduced pin count interface. | |
| 12 | + RMII selects 100 Base-tx reduced pin count interface. | |
| 13 | + | |
| 14 | +CONFIG_FEC_MXC_SWAP_PACKET | |
| 15 | + Forced on iff MX28. | |
| 16 | + Swaps the bytes order of all words(4 byte units) in the packet. | |
