2013-04-08stmmac: code tidy-upGiuseppe CAVALLARO
This patch tidies up the code. I have run Linden (and verified with checkpatch) many part of the driver trying to reorganize some sections respecting the codying-style rules in the points where it was not done.

2013-03-26stmmac: support extend descriptorsGiuseppe CAVALLARO
This patch is to support the extend descriptors available in the chips newer than the 3.50. In case of the extend descriptors cannot be supported, at runtime, the driver will continue to work using the old style. In detail, this support extends the main descriptor structure adding new descriptors: 4, 5, 6, 7. The desc4 gives us extra information about the received ethernet payload when it is carrying PTP packets or TCP/UDP/ICMP over IP packets. The descriptors 6 and 7 are used for saving HW L/H timestamps (PTP). V2: this new version removes the Koption added in the first implementation because all the checks now to verify if the extended descriptors are actually supported happen at probe time.

2011-10-27stmmac: update normal descriptor structure (v2)Giuseppe CAVALLARO
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).
