0006 This enables support for configuring Data Center Bridging (DCB)
0007 features on DCB capable Ethernet adapters via rtnetlink. Say 'Y'
0008 if you have a DCB capable Ethernet adapter which supports this
0009 interface and you are connected to a DCB capable switch.

0011 DCB is a collection of Ethernet enhancements which allow DCB capable
0012 NICs and switches to support network traffic with differing
0013 requirements (highly reliable, no drops vs. best effort vs. low
0014 latency) to co-exist on Ethernet.
0015
0016 DCB features include:
0017 Enhanced Transmission Selection (aka Priority Grouping) - provides a
0018 framework for assigning bandwidth guarantees to traffic classes.
0019 Priority-based Flow Control (PFC) - a MAC control pause frame which
0020 works at the granularity of the 802.1p priority instead of the
0021 link (802.3x).
0022
0023 If unsure, say N.
