Subject: dcb: Add stub routines for !CONFIG_DCB
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=27737aa3a9f65012b3656b71e0ff230a4811da4d;p=~shefty%2Frdma-dev.git

dcb: Add stub routines for !CONFIG_DCB

To avoid ifdefs in the other code that supports DCB notifiers
add stub routines. This method seems popular in other net code
for example 8021Q.
