The PHY_SWAP and PHY_ADDR_SWAP bits are initialized differently by different versions of the bootloader. This leads to broken ethernet connection with OpenWrt on some boards. Turn both SWAP bits OFF on these boards to make it consistent regardless of the bootloader used. Based on a patch by Michel Stempin <michel.stempin@wanadoo.fr>.
