Say 'Y' 8 if you have a DCB capable Ethernet adapter which supports this 9 interface and you are connected to a DCB capable switch. 10 11 DCB is a collection of Ethernet enhancements which allow DCB capable 12 NICs and switches to support network traffic with differing 13 requirements (highly reliable, no drops vs. best effort vs. low 14 latency) to co-exist on Ethernet. 15 16 DCB features include: 17 Enhanced Transmission Selection (aka Priority Grouping) - provides a 18 framework for assigning bandwidth guarantees to traffic classes. 19 Priority-based Flow Control (PFC) - a MAC control pause frame which 20 works at the granularity of the 802.1p priority instead of the 21 link (802.3x). 22 23 If unsure, say N.
