When setting mstpctl params from user given fdelay and maxage,
ifreload and ifup is setting maxage before fdelay.
Since there is a check for (Bridge Foward Delay - 1 second) >= Bridge Max Age
fdelay must be set before maxage because the fdelay is a default value.

Once mstpctl-portbpdufilter or mstpctl-bpduguard is enabled for

does not toggle the mstpctl state back to no.
The root cause of this problem is that "ifreload" does not check default settings for MSTP configuration
for bridge ports and use a default when that setting is removed from the configuration.
This patch adds a check in the existing loop on attribute values.
If there is no configured value, we check to see if a default exists.
self._modinfo['attrs'][attrname]['default'] exists.
If it exists and it is different then the currently running value
we reset the attribute to its default. This is what a customer would expect if
they removed a configured value.
(also added test in cl-tests to check this functionality)

Testing Done: Tested regex parsing failures
This is mostly a cosmetic fix. we were failing with weird/unclear errors
on unable to parse regex expressions correctly.
This patch mainly adds the interface name to the message and plus adds
an info message showing the actual regex being used in searches.
example config:

auto br-roopa

bridge-vlan-aware yes
bridge-ports regex '(\\Aswp3\\Z|\\Aswp4\\Z)'

parenthesis)
after the patch (not pretty but easier to debug)

Testing Done: Tested the problem case mentioned in the bug (Plan to
re-work the fix a bit for 2.5.5)
problem:
mstp parameters can be specified under the port or under the bridge
When they are specified under the bridge, there should be no problem
(When you process the bridge, all things on the bridge port are set in
order)
When they are specified under the port:
we check if the bridge is up, if yes, and stp is already configured,
we process mstpctl settings
This check today only checks running stp_state
We should also check the user configured stp state for the bridge
Note that the problem exists only if the bridge and ports are
already up and user executes ifup again and when we need to re-evaluate
the bridge port settings
solution:
When the bridge port is being checked for mstp settings, not only
check running stp state, but also check user specified stp state and
correct bridge stp state before proceeding with mstp configuration
Few things to note with this patch:
- If user changed stp state on bridge to 'on', and did `ifup
<bridge_port>'`,
though the user has not ifup'ed the bridge yet, the bridge stp state
will be applied (very few people will run into this and practically this
should not be a problem atall. But from correctness POV it is
a voilation. ).
- To avoid this, the other solution would have been to let the bridge
port code be as is, but handle this during bringing up the bridge,
but, this can confuse the user, because when processing the
bridge_port, you will still throw warnings even if the port stp config
is later reapplied when the bridge comes up
- note that the patch only handles the case when stp state is not on and
somebody turned it on. For the case where stp state was on and somebody
turned it off, this patch wont throw warnings for the mstpctl config. But
it will not cause any issues because once stp is off things will be ok
everywhere. I want to keep any changes here out of this patch. I will
document this in the bug...and see if i can handle this in 2.5.5

Testing Done: tested bridge and bonds with interfaces with configs
Both bridge and mstpctl modules set priv_flags on interfaces
that have configs (like link-speed) even when used as bridge-ports.
And this collision causes statemanager.ifaceobj_sync() to never get called
because ifaceobj.priv_flags is 1 (we return immediately):
The fix was to create a new iface module_flags array to carry module info.
