Jeff Kirsher 7a6b6f515f DCB: fix kconfig option 
Since the netlink option for DCB is necessary to actually be useful,
simplified the Kconfig option.  In addition, added useful help text for the
Kconfig option.

config DCB 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.
