The PSC sync change interrupt can fire multiple times while the link is
down, which is caused by noise on the serdes lines. As this isn't
information we make use of, it's pointless having the interrupt enabled.

The netdev core always ensures that the rtnl lock is held while calling
the ndo_open() and ndo_stop() methods. However, the suspend/resume paths
do not hold the rtnl lock. phylink will expect the rtnl lock to be held
when the MAC driver calls it, so we end up with kernel warnings. Take
the lock to ensure that these functions are called in a consistent
manner.

Add SCTP ACK tracking trace event to trace the changes of SCTP

It is used for debugging SCTP congestion control algorithms,
and will replace sctp_probe module.

Note that this event a bit tricky. Since this consists of 2
events (sctp_probe and sctp_probe_path) so you have to enable
both events as below.

  # cd /sys/kernel/debug/tracing
  # echo 1 > events/sctp/sctp_probe/enable
  # echo 1 > events/sctp/sctp_probe_path/enable

Or, you can enable all the events under sctp.

  # echo 1 > events/sctp/enable

Since sctp_probe_path event is always invoked from sctp_probe
event, you can not see any output if you only enable
sctp_probe_path.
