Pradyumn Rahar 921fe6ec68 The valid range of arp_missed_max according to the kernel is 1-255,
while the default value of the same in NM is 0, which causes warnings to
arise, change this default value.

Allow the range in NM to stay 0-255 as 0 is used to indicate arp_missed_max
is unset (for modes that don't support the setting), however do not let it
be set beyond the kernel permissible range for the modes that support it, set
it to the kernel default of 2 instead.

Do not apply or reapply the arp_missed_max setting when it is not
supported.

libnm-platform

A static helper library that provides NMPlatform and other utils. This is NetworkManager's internal netlink library, but also contains helpers for sysfs, ethtool and other kernel APIs.

NMPlaform is also a cache of objects of the netlink API: NMPCache and NMPObject. These objects are used throughout NetworkManager also for generally tracking information about these types. For example, NMPlatformIP4Address (the public part of a certain type of NMPObject) is not only used to track platform addresses from netlink in the cache, but to track information about IPv4 addresses in general.

This depends on the following helper libraries
