  	bool "Data Center Bridging support"

  	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.
