Giuseppe CAVALLARO 3c20f72f91 stmmac: update normal descriptor structure (v2) ... 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).
