Subject: [PATCH 2/5] network: Fix type and respect name when rendering vlan in
sysconfig. (#541)
RH-Author: Eduardo Terrell Ferrari Otubo (eterrell)
RH-MergeRequest: 10: ifup bond0.504 Error: Connection activation failed: No suitable device found for this connection [rhel-8.3.0.z]
RH-Commit: [1/1] fe8bd8bc184d2391b3f9ac6af80e231649d6019a (eterrell/cloud-init)
RH-Bugzilla: 1890551
commit 8439b191ec2f336d544cab86dba2860f969cd5b8
Author: Eduardo Otubo <otubo@redhat.com>

network: Fix type and respect name when rendering vlan in sysconfig. (#541)
Prior to this change, vlans were rendered in sysconfig with
'TYPE=Ethernet', and incorrectly rendered the PHYSDEV based on
the name of the vlan device rather than the 'link' provided
in the network config.
The change here fixes:
* rendering of TYPE=Ethernet for a vlan
* adds a warning if the configured device name is not supported
per the RHEL 7 docs "11.5. Naming Scheme for VLAN Interfaces"
LP: #1788915
LP: #1826608
RHBZ: #1861871
Conflicts:
* A hunk on cloudinit/net/sysconfig.py could not apply cleanly as it
depends on a verification on the distro flavor, which is not implemented
on cloud-init-19.4.
* Couple of hunks could not apply cleanly on tests/unittests/test_net.py
because the definition of unit test response moved a little bit.
