---help---
- This option turns on the netlink interface
- (dcbnl) for Data Center Bridging capable devices.
+ 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.
