> This patch updates the normal descriptor structure
> to work fine on new GMAC Synopsys chips.
> 
> Normal descriptors were designed on the old MAC10/100
> databook 1.91 where some bits were reserved: for example
> the tx checksum insertion and rx checksum offload.
> 
> The patch maintains the back-compatibility with old
> MAC devices (tested on STx7109 MAC10/100) and adds new
> fields that actually new GMAC devices can use.
> 
> For example, STx7109 (MAC10/100) will pass from the platform
>   tx_coe = 0, enh_desc = 0, has_gmac = 0.
> A platform like Loongson1B (GMAC) will pass:
>   tx_coe = 1, enh_desc = 0, has_gmac = 1.
> 
> Thanks to Kelvin, he enhanced the normal descriptors for
> GMAC (on MIPS Loongson1B platform).
