Add per port priority support for bond active port re-selection during
failover. A higher number means a higher priority in selection. The
primary port still has the highest priority. This option is only
compatible with active-backup, balance-tlb and balance-alb modes.

sysfs is deprecated and kernel will not add new bond port options to
sysfs. Netlink is a stable API and therefore is the right method to
communicate with kernel in order to set the link options.

The correct variable for queue-id in ifcfg is BOND_PORT_QUEUE_ID.

A workaround for a nftables issue ([1]). I don't know why that matters.

Names are important. The previous name was counter intuitive for what
the behavior was.

It translates to a plain memcmp() as the argument is a string literal.

The previous logging happened, when the value did not change. Log
instead, when the value changes.

Fixes: 86bb09c93be3 ('dns: generate correct search domain for hostnames on non-public TLD')

dns-manager uses the Mozilla Public Suffix List to determine an
appropriate search domain when generating /etc/resolv.conf. It is
presumed that if the hostname is "example.com", the user does not want
to automatically search "com" for unqualified hostnames, which is
reasonable.  To implement that, prior to the fix, domain_is_valid()
implicitly used the PSL "prevailing star rule", which had the
consequence of assuming that any top-level domain (TLD) is public
whether it is on the official suffix list or not. That meant
"example.local" or "example.localdomain" would not result in searching
"local" or "localdomain" respectively, but rather /etc/resolv.conf would
contain the full hostname "example.local" as the search domain and not
give users what they expect.  The fix here uses the newer PSL API
function that allows us to turn off the "prevailing star rule" so that
"local" and "localdomain" are NOT considered public TLDs because they
are not literally on the suffix list. That in turn gives us the search
domain "local" or "localdomain" in /etc/resolv.conf and allows
unqualified hostname lookups "e.g., resolvectl query example" to find
example.local while example.com still maintains the previous behavior
(i.e., search domain of "example.com" rather than "com").
