|
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.
