From 530bd8e1e68973c0b0f67e60c5520d32bb2628ad Mon Sep 17 00:00:00 2001 From: Pierre Pfister Date: Tue, 10 May 2016 17:11:22 +0100 Subject: VPP-69: Create fib or bridge domain with arbitrary ID It appeared to me that it might be usefull to allow users to create fibs or bridge domains without a complete knowledge of the current used IDs. These changes define fib and bridge domain constructors when the provided ID is ~0. In such a case, an unused ID is used to create a new fib or bridge domain.
