662306a36Sopenharmony_ci	  This enables support for configuring Data Center Bridging (DCB)
762306a36Sopenharmony_ci	  features on DCB capable Ethernet adapters via rtnetlink.  Say 'Y'
862306a36Sopenharmony_ci	  if you have a DCB capable Ethernet adapter which supports this
962306a36Sopenharmony_ci	  interface and you are connected to a DCB capable switch.

1162306a36Sopenharmony_ci	  DCB is a collection of Ethernet enhancements which allow DCB capable
1262306a36Sopenharmony_ci	  NICs and switches to support network traffic with differing
1362306a36Sopenharmony_ci	  requirements (highly reliable, no drops vs. best effort vs. low
1462306a36Sopenharmony_ci	  latency) to co-exist on Ethernet.
1562306a36Sopenharmony_ci
1662306a36Sopenharmony_ci	  DCB features include:
1762306a36Sopenharmony_ci	    Enhanced Transmission Selection (aka Priority Grouping) - provides a
1862306a36Sopenharmony_ci	      framework for assigning bandwidth guarantees to traffic classes.
1962306a36Sopenharmony_ci	    Priority-based Flow Control (PFC) - a MAC control pause frame which
2062306a36Sopenharmony_ci	      works at the granularity of the 802.1p priority instead of the
2162306a36Sopenharmony_ci	      link (802.3x).

2362306a36Sopenharmony_ci	  If unsure, say N.
