Re: [libvirt] [PATCH] macvtap: Fix error return values to -1 instead of 1

From: Roopa Prabhu <roprabhu(a)cisco.com&gt; Fixes some cases where 1 was being returned instead of -1. There are still some inconsistencies in the file with respect to what the return variable is initialized to. Can be fixed as a separate patch if needed. The scope of this patch is just to fix the return value 1. Did some basic sanity test. Signed-off-by: Roopa Prabhu <roprabhu(a)cisco.com&gt; Reported-by: Eric Blake <eblake(a)cisco.com&gt;
