5 | This enables support for configuring Data Center Bridging (DCB) |
6 | features on DCB capable Ethernet adapters via rtnetlink. Say 'Y' | |
7 | if you have a DCB capable Ethernet adapter which supports this | |
8 | interface and you are connected to a DCB capable switch. | |
9 | ||
10 | DCB is a collection of Ethernet enhancements which allow DCB capable | |
11 | NICs and switches to support network traffic with differing | |
12 | requirements (highly reliable, no drops vs. best effort vs. low | |
13 | latency) to co-exist on Ethernet. | |
14 | ||
15 | DCB features include: | |
16 | Enhanced Transmission Selection (aka Priority Grouping) - provides a | |
17 | framework for assigning bandwidth guarantees to traffic classes. | |
18 | Priority-based Flow Control (PFC) - a MAC control pause frame which | |
19 | works at the granularity of the 802.1p priority instead of the | |
20 | link (802.3x). | |
