14 | In This Release | ||
15 | =============== | ||
16 | |||
17 | This file describes the ixgbevf Linux* Base Driver for Intel Network | ||
18 | Connection. | ||
19 | |||
20 | The ixgbevf driver supports 82599-based virtual function devices that can only | ||
21 | be activated on kernels with CONFIG_PCI_IOV enabled. | ||
22 | |||
23 | The ixgbevf driver supports virtual functions generated by the ixgbe driver | ||
24 | with a max_vfs value of 1 or greater. | ||
25 | |||
26 | The guest OS loading the ixgbevf driver must support MSI-X interrupts. | ||
27 | |||
28 | VLANs: There is a limit of a total of 32 shared VLANs to 1 or more VFs. | ||
29 | |||
30 | Identifying Your Adapter | ||
31 | ======================== | ||
32 | |||
33 | For more information on how to identify your adapter, go to the Adapter & | ||
34 | Driver ID Guide at: | ||

1 | Thin-streams and TCP | ||
2 | ==================== | ||
3 | A wide range of Internet-based services that use reliable transport | ||
4 | protocols display what we call thin-stream properties. This means | ||
5 | that the application sends data with such a low rate that the | ||
6 | retransmission mechanisms of the transport protocol are not fully | ||
7 | effective. In time-dependent scenarios (like online games, control | ||
8 | systems, stock trading etc.) where the user experience depends | ||
9 | on the data delivery latency, packet loss can be devastating for | ||
10 | the service quality. Extreme latencies are caused by TCP's | ||
11 | dependency on the arrival of new data from the application to trigger | ||
12 | retransmissions effectively through fast retransmit instead of | ||
13 | waiting for long timeouts. | ||
14 | |||
15 | After analysing a large number of time-dependent interactive | ||
16 | applications, we have seen that they often produce thin streams | ||
17 | and also stay with this traffic pattern throughout its entire | ||
18 | lifespan. The combination of time-dependency and the fact that the | ||
19 | streams provoke high latencies when using TCP is unfortunate. | ||
20 | |||
21 | In order to reduce application-layer latency when packets are lost, | ||
22 | a set of mechanisms has been made, which address these latency issues | ||
23 | for thin streams. In short, if the kernel detects a thin stream, | ||
24 | the retransmission mechanisms are modified in the following manner: | ||
25 | |||
26 | 1) If the stream is thin, fast retransmit on the first dupACK. | ||
27 | 2) If the stream is thin, do not apply exponential backoff. | ||
28 | |||
29 | These enhancements are applied only if the stream is detected as | ||
30 | thin. This is accomplished by defining a threshold for the number | ||
31 | of packets in flight. If there are less than 4 packets in flight, | ||
32 | fast retransmissions can not be triggered, and the stream is prone | ||
33 | to experience high retransmission latencies. | ||
34 | |||
35 | Since these mechanisms are targeted at time-dependent applications, | ||
36 | they must be specifically activated by the application using the | ||
37 | TCP_THIN_LINEAR_TIMEOUTS and TCP_THIN_DUPACK IOCTLS or the | ||
38 | tcp_thin_linear_timeouts and tcp_thin_dupack sysctls. Both | ||
39 | modifications are turned off by default. | ||

27 | If this property is not present, an optimal CAN | ||

29 | clock will be selected. If this is not possible, | ||
30 | the reference clock will be used. | ||
31 | |||
