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.

new capabilities and initial support of new HW. The changes are mostly in
qed, and include changes in the FW interface files, as well as updating the
FW initialization and debug collection code. The protocol drivers have
minor functional changes for this firmware.

Patch 1 Rearranges and refactors the FW interface files in preparation of
the new FW (no functional change).
Patch 2 Prepares the code for support of new HW (no functional change).
Patch 3 Actual utilization of the new FW.
Patch 4 Advances drivers' version.

v3->v4:
Fix a compilation issue which was reported by krobot (dependency on CRC8).

inet_diag currently provides less/greater than or equal operators for
comparing ports when filtering sockets. An equal comparison can be
performed by combining the two existing operators, or a user can for
example request a port range and then do the final filtering in
userspace. However, these approaches both have drawbacks. Implementing
equal using LE/GE causes the size and complexity of a filter to grow
quickly as the number of ports increase, while it on busy machines would
be great if the kernel only returns information about relevant sockets.

This patch introduces source and destination port equal operators.
INET_DIAG_BC_S_EQ is used to match a source port, INET_DIAG_BC_D_EQ a
destination port, and usage is the same as for the existing port
operators.  I.e., the port to match is stored in the no-member of the
next inet_diag_bc_op-struct in the filter.

as still in the host queue and never be retransmitted. This happend
when dev_requeue_skb() called from qdisc_restart().
