12 | The IEEE 1588 standard defines a method to precisely | |
13 | synchronize distributed clocks over Ethernet networks. The | |
14 | standard defines a Precision Time Protocol (PTP), which can | |
15 | be used to achieve synchronization within a few dozen | |
16 | microseconds. In addition, with the help of special hardware | |
17 | time stamping units, it can be possible to achieve | |
18 | synchronization to within a few hundred nanoseconds. | |

20 | This driver adds support for PTP clocks as character | |
21 | devices. If you want to use a PTP clock, then you should | |
22 | also enable at least one clock driver as well. | |
23 | ||
24 | To compile this driver as a module, choose M here: the module | |
25 | will be called ptp. | |

33 | This driver adds support for using the eTSEC as a PTP | |
34 | clock. This clock is only useful if your PTP programs are | |
35 | getting hardware time stamps on the PTP Ethernet packets | |

71 | In order for this to work, your MAC driver must also | |
6b2aac42 | 72 | implement the skb_tx_timestamp() function. |
