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