| Jeff Kirsher | 7a6b6f5 | 2008-11-25 01:02:08 -0800 | [diff] [blame] | 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). |
