Only caller of get_phy_id() is get_phy_device(). There a PHY ID of
0xffffffff is translated back to -ENODEV. So we can avoid some
overhead by returning -ENODEV directly.

Since recent changes to the phylib state machine state PHY_CHANGELINK
isn't used any longer. Therefore let's remove it.

If we make sure all listeners have these fields cleared, then a clone
will also inherit zero values.

If we make sure all listeners have proper tp->rack value,
then a clone will also inherit proper initial value.
Note that fresh sockets init tp->rack from tcp_init_sock()

All listeners have this field cleared already, since tcp_disconnect()
clears it and newly created sockets have also a zero value here.
So a clone will inherit a zero value here.

Passive connections can inherit proper value by cloning,
if we make sure all listeners have the proper values there.
tcp_disconnect() was setting snd_cwnd to 2, which seems
quite obsolete since IW10 adoption.
Also remove an obsolete comment.

If we make sure a listener always has its mdev_us
field set to TCP_TIMEOUT_INIT, we do not need to rewrite
this field after a new clone is created.
tcp_disconnect() is very seldom used in real applications.

New sockets have this field cleared, and tcp_disconnect()
calls tcp_write_queue_purge() which among other things
also clear tp->packets_out
So a listener is guaranteed to have this field cleared.

New sockets get the field set to TCP_INFINITE_SSTHRESH in tcp_init_sock()
In case a socket had this field changed and transitions to TCP_LISTEN
state, tcp_disconnect() also makes sure snd_ssthresh is set to
TCP_INFINITE_SSTHRESH.
So a listener has this field set to TCP_INFINITE_SSTHRESH already.

There is an if statement and a return statement that are incorrectly
indented. Fix these. Also replace the assignment-in-if statements
to assignment followed by an if to keep to the coding style.

In some testing scenarios, dst/route cache can fill up so quickly
that even an explicit GC call occasionally fails to clean it up. This leads
to sporadically failing calls to dst_alloc and "network unreachable" errors
to the user, which is confusing.
This patch adds a diagnostic message to make the cause of the failure
easier to determine.

In the current implementation, on interface down we disabled NAPI and
then manually drained any remaining ingress frames. This could lead
to a situation when, under heavy traffic, the data availability
notification for some of the channels would not get rearmed correctly.
Change the implementation such that we let all remaining ingress frames
be processed as usual and only disable NAPI once the hardware queues
are empty.
We also add a wait on the Tx side, to allow hardware time to process
all in-flight Tx frames before issueing the disable command.
