Subject: net: vrf: do not allow table id 0
From: David Ahern <dsa@xxxxxxxxxxxxxxxxxxx>
[ Upstream commit 24c63bbc18e25d5d8439422aa5fd2d66390b88eb ]
Frank reported that vrf devices can be created with a table id of 0.
This breaks many of the run time table id checks and should not be
allowed. Detect this condition at create time and fail with EINVAL.
Fixes: 193125dbd8eb ("net: Introduce VRF device driver")
