functionality beyond TAP interface interaction.
* The class includes general logic for polling and sending packets to
file descriptors, making it suitable for wider use cases.

There are only three calls to this method, and two of them
are with a list of 1 address which means it's simpler inlined.
The last call will be replaced with calls to RouteController

If we run an iterations test, TCP connections opened by previous tests
won't be closed immediately. They will stay in the TIME_WAIT state for
120 seconds before closed. Netfilter socket listens to both
NF_NETLINK_CONNTRACK_NEW and NF_NETLINK_CONNTRACK_DESTROY groups.
There is a tiny time gap between socket creation and sending dump
request to kernel. If an old TCP connection happened to be closed in
this time gap, listening socket would see a DESTROY message before
seeing the NEW messages triggered by dump request.
The current test only parsing the first contrack message in the read
buffer, so it will only find the DESTROY message and ignore all of the
following NEW messages. It does a netfilter socket dump, but does not
check whether the dump produces reasonable output. Now that we have
the ability to parse conntrack messages, do more in-depth checking.

The defaults can be used to enable/disable connectivity next targets
depending on the branch, while minimizing merge conflicts.
The "next" target may use unstable APIs. It need to be disabled in the
branch which only have the last stable SDK available.

move netd.c and clatd.c to it, the folder should be moved to the upper

other connectivity code besides to tethering are justified to use it.

Add separate testing for unicast and multicast RAs.
Make the test more realistic by:
- Enabling forwarding. This ensures that the daemon actually
receives the RS.
- Adding a link-local route. This ensures that the daemon is
actually able to send a unicast response.

When forwarding is on, DadProxyTest fails because forwarding
disables optimistic addresses. This results in the DAD proxy
getting EADDRNOTAVAIL.
Forwarding is on quite often on real hardware because many
solutions for wifi calling use forwarding.
Fix the test to retry after two seconds if the packet is not
forwarded on the first attempt.
It would also be possible to make this work more reliably in the
test by simply disabling DAD or disabling forwarding. However,
because DAD does happen in real usage (downstream interfaces
always disable DAD, but upstream interfaces don't), that seems
risky. For example, if the test disabled DAD, it would not catch
bugs where the DAD proxy crashed or stopped forwarding if it got
EADDRNOTAVAIL.
Test: atest TetheringPrivilegedTests on coral, which has forwarding on
