Yes, it needs to run twice because the first run doesn't yet produce the

_nm_utils_hwaddr_aton() is only a wrapper around nm_utils_hexstr2bin_full().
But it abstracts the "right" parameters for what we consider a valid MAC
address and what not. As such, this function is useful.
Move it to "shared/" and replace the dupicate macro hwaddr_aton() with
it.
nm_setting_ip_config_next_valid_dns_option() API was added in libnm 1.2, but
it was never exported in the ABI of libnm. It thus was unusable, and any user
trying to link against it would have been unable to do so.
Hide the API now entirely. It doesn't seem a very nice API. If we want to
allow the user to validate option names, we should expose such a function
to validate an option (not to fetch the next valid option from a
profile).

More general purpose API for generic options of settings.
The predicate function is also nicely usable via bindings.
One question is about the form of the predicate. In this case,
it is convenient to pass nm_ethtool_optname_is_coalesce(). On the
other hand, it's not very flexible as it does not accept a user
data argument. Use NMUtilsPredicateStr here, which is not flexible
but convenient for where it's used.
NMSettingEthtool is implemented using "gendata", meaning a hash
of GVariant. This is different from most other settings that have
properties implemented as GObject properties. There are two reasons
for this approach:
- The setting is transferred via D-Bus as "a{sv}" dictionary.
By unpacking the dictionary into GObject properties, the setting
cannot handle unknown properties. To be forward compatible (and
due to sloppy programming), unknown dictionary keys are silently
ignored when parsing a NMSetting. That is error prone and also
prevents settings to be treated loss-less.
Instead, we should at first accept all values from the dictionary.
Only in a second step, nm_connection_verify() rejects invalid settings
with an error reason. This way, the user can create a NMSetting,
but in a separate step handle if the setting doesn't verify.
"gendata" solves this by tracking the full GVariant dictionary.
This is still not entirely lossless, because multiple keys are
combined.
This is for example interesting if an libnm client fetches a connection
from a newer NetworkManager version. Now the user can modify the
properties that she knows about, while leaving all unknown
properties (from newer versions) in place.
- the approach aims to reduce the necessary boiler plate to create
GObject properties. Adding a new property should require less new code.
This approach was always be intended to be suitable for all settings, not only
NMSettingEthtool. We should not once again try to add API like
nm_setting_ethtool_set_feature(), nm_setting_ethtool_set_coalesce(), etc.
Note that the option name already fully encodes whether it is a feature,
a coalesce option, or whatever. We should not have
"nm_setting_set_$SUB_GROUP (setting, $ONE_NAME_FROM_GROUP)" API, but
simply "nm_setting_option_set (setting, $OPTION)" accessors.
Also, when parsing a NMSettingEthtool from a GVariant, then a feature
option can be any kind of variant. Only nm_setting_verify() rejects
variants of the wrong type. As such, nm_setting_option_set*() also
doesn't validate whether the variant type matches the option. Of course,
if you set a value of wrong type, verify() will reject the setting.
Add new general purpose API for this and expose it for NMSetting.
We are going to expose some of this API in libnm.
The name "gendata" (for "generic data") is not very suited. Instead,
call the public API nm_setting_option_*(). This also brings no naming
conflict, because currently no API exists with such naming.
Rename the internal API, so that it matches the API that we are going
to expose next.
This was intended for when the gendata hash should be converted
to/from a GValue/GHashTable. This would have been used, if
we also would have added a GObject property that exposes
the hash. But that was never done (at least not for NMSettingEthtool
and not yet).
This code is not used. If you ever need it, revert the patch
or implement it anew.
This function is not used nor does it seem useful.
Either you only need the names (nm_setting_gendata_get_all_names())
or you need the names and values together (_nm_setting_gendata_get_all()).
Getting the values without knowing the corresponding name makes
little sense. If you need it, call _nm_setting_gendata_get_all()
instead.
The filter function in nm_setting_gendata_clear_all() is useful
for when you want to only clear values according to a predicate,
if no such function is supplied all values will be cleared.

Add '_nm_setting_bond_get_option_or_default()' and move all the custom
policies applied by NM for bond options in there.
One such example of a custom policy is to set 'miimon' to 0 (instead of its
default value of 100) if 'arp_interval' is explicitly enabled
and 'miimon' is not.
This means removing every piece of logic from
nm_setting_bond_add_option() which used to clear out 'arp_interval' and
'arp_ip_target' if 'miimon' was set or clear out 'miimon' along with
'downdelay', 'updelay' and 'miimon' if 'arp_interval' was set.
This behaviour is a bug since the kernel allow setting any combination
of this options for bonds and NetworkManager should not limit the user
to do so.
Also use 'set_bond_attr_or_default()' instead of 'set_bond_attr()' as
the former calls '_nm_setting_bond_get_option_or_default()' to implement
the right logic to retrieve bond options according to current bond
configuration.
Doing 'verify()' with options such as 'miimon' and 'num_grat_arp' set to
arbitrary values it's not consistent with what NetworkManager does to
bond options when activating the bond through 'apply_bonding_config()'
(at a later stage) because the said values do not
correspond to what the default values for those options are.
This leads to an inconsistency with the 'miimon' parameter for example,
where 'verify()' is done while assuming it's 0 if not set but its
default value is actually 100.
