Well the patch has coding style problems, for one:

>> +			dev->features |= (EMAC_APM821XX_REQ_JUMBO_FRAME_SIZE
>> +					| EMAC_FTR_APM821XX_NO_HALF_DUPLEX
>> +					| EMAC_FTR_460EX_PHY_CLK_FIX);

Should be:

>> +			dev->features |= (EMAC_APM821XX_REQ_JUMBO_FRAME_SIZE |
>> +					  EMAC_FTR_APM821XX_NO_HALF_DUPLEX |
>> +					  EMAC_FTR_460EX_PHY_CLK_FIX);

And this:

>> +		dev->phy_feat_exc = (SUPPORTED_1000baseT_Half
>> +					| SUPPORTED_100baseT_Half
>> +					| SUPPORTED_10baseT_Half);

Should be:

>> +		dev->phy_feat_exc = (SUPPORTED_1000baseT_Half |
>> +				     SUPPORTED_100baseT_Half |
>> +				     SUPPORTED_10baseT_Half);
