| 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. |
