From 33dbabc4a7f7bd72313c73a3c199f31f3900336f Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Thu, 20 Nov 2008 21:08:19 -0800 Subject: DCB: Add interface to query # of TCs supported by device Adds interface for Data Center Bridging (DCB) to query (and set if supported) the number of traffic classes currently supported by the device for the two (DCB) features: priority groups (PG) and priority flow control (PFC).
