Say 'Y' 7*7a6b6f51SJeff Kirsher if you have a DCB capable Ethernet adapter which supports this 8*7a6b6f51SJeff Kirsher interface and you are connected to a DCB capable switch. 9*7a6b6f51SJeff Kirsher 10*7a6b6f51SJeff Kirsher DCB is a collection of Ethernet enhancements which allow DCB capable 11*7a6b6f51SJeff Kirsher NICs and switches to support network traffic with differing 12*7a6b6f51SJeff Kirsher requirements (highly reliable, no drops vs. best effort vs. low 13*7a6b6f51SJeff Kirsher latency) to co-exist on Ethernet. 14*7a6b6f51SJeff Kirsher 15*7a6b6f51SJeff Kirsher DCB features include: 16*7a6b6f51SJeff Kirsher Enhanced Transmission Selection (aka Priority Grouping) - provides a 17*7a6b6f51SJeff Kirsher framework for assigning bandwidth guarantees to traffic classes. 18*7a6b6f51SJeff Kirsher Priority-based Flow Control (PFC) - a MAC control pause frame which 19*7a6b6f51SJeff Kirsher works at the granularity of the 802.1p priority instead of the 20*7a6b6f51SJeff Kirsher link (802.3x). 212f90b865SAlexander Duyck 222f90b865SAlexander Duyck If unsure, say N. 23
