329 | 7) TODO: | 329 | 7) Extended descriptors |
330 | The extended descriptors give us information about the receive Ethernet payload | ||
331 | when it is carrying PTP packets or TCP/UDP/ICMP over IP. | ||
332 | These are not available on GMAC Synopsys chips older than the 3.50. | ||
333 | At probe time the driver will decide if these can be actually used. | ||
334 | This support also is mandatory for PTPv2 because the extra descriptors 6 and 7 | ||
335 | are used for saving the hardware timestamps. | ||
336 | |||
337 | 8) Precision Time Protocol (PTP) | ||
338 | The driver supports the IEEE 1588-2002, Precision Time Protocol (PTP), | ||
339 | which enables precise synchronization of clocks in measurement and | ||
340 | control systems implemented with technologies such as network | ||
341 | communication. | ||
342 | |||
343 | In addition to the basic timestamp features mentioned in IEEE 1588-2002 | ||
344 | Timestamps, new GMAC cores support the advanced timestamp features. | ||
345 | IEEE 1588-2008 that can be enabled when configure the Kernel. | ||

347 | 9) SGMII/RGMII supports | ||
348 | New GMAC devices provide own way to manage RGMII/SGMII. | ||
349 | This information is available at run-time by looking at the | ||
350 | HW capability register. This means that the stmmac can manage | ||
351 | auto-negotiation and link status w/o using the PHYLIB stuff | ||
352 | In fact, the HW provides a subset of extended registers to | ||
353 | restart the ANE, verify Full/Half duplex mode and Speed. | ||
354 | Also thanks to these registers it is possible to look at the | ||
355 | Auto-negotiated Link Parter Ability. | ||
