Change details:
 - This patch contains the changes as a result of redesigning of Tx, Rx data
   path setup. In the old design, setting up Txqs, Rxqs were done in the driver.
   With the new design, most of the hardware setup steps for the Txq, Rxqs are
   moved to FW. Host driver issues commands to FW through the message queue to
   setup/teardown tx, rx data path. FW performs necessary steps and responds
   back to the driver with a status.
 - As a result of this redesign, the state machine implementation for Tx, Rx
   objects have changed significantly. Instead of doing the raw register access,
   these state machines mostly send a command to FW and wait for response and
   take the next action. In addition to tx, rx datapath setup, this patch also
   deals with rx filter configuration - such as unicast address, multicast
   address, vlan filter, promiscuous mode etc.

Change details:
 - This patch contains the messages, opcodes and structure format for the
   messages and responses exchanged between driver and the FW. In addition
   this patch contains the state machine implementation for Ethport, Enet,
   IOCEth.
 - Ethport object is responsible for receiving link state events, sending
   port enable/disable commands to FW.
 - Enet object is responsible for synchronizing initialization/teardown of
   tx & rx datapath configuration.
 - IOCEth object is responsible for init/un-init of IO Controller in the
   adapter which runs the FW.
 - This patch also contains code for initialization and resource assignment
   for Ethport, Enet, IOCEth, Tx, Rx objects.

Change details:
 - Currently modules communicate with the FW using 32 byte command and
   response register. This limits the size of the command and response
   messages exchanged with the FW to 32 bytes. We need a mechanism to
   exchange the comamnds and responses exchange with FW that exceeds 32 bytes.

 - MSGQ implementation provides that facility. It removes the assumption that
   command/response queue size is precisely calculated to accommodate all
   concurrent FW commands/responses. The queue depth is made variable now, defined
   by a macro. A waiting command list is implemented to hold all the commands
   when there is no place in the command queue. Callback is implemented for
   each command entry to invoke the module posting the command, when there is
   space in the command queue and the command was finally posted to the queue.
   Module/Object information is embedded in the response for tracking purpose.

The dp83640 buffers receive time stamps from special PHY status frames,
matching them to received PTP packets in a work queue. Because the timeout
for orphaned time stamps is so long and the buffer is so small, the driver
can drop time stamps under moderate PTP traffic.

This commit fixes the issue by decreasing the timeout to (at least) one
timer tick and increasing the buffer size.

After resetting the time, the PPS signals on the FIPER output channels
are incorrectly offset from the clock time, as can be readily verified
by a looping back the FIPER to the external time stamp input.

Despite its name, setting the "Fiper Realignment Disable" bit seems to
fix the problem, at least on the P2020.

Also, following the example code from the Freescale BSP, it is not really
necessary to disable and re-enable the timer in order to reprogram the
FIPER. (The documentation is rather unclear on this point. It seems that
writing to the alarm register also disables the FIPER.)

TCP in some cases uses different global (raw) socket
to send RST and ACK. The transparent flag is not set there.
Currently, it is a problem for rerouting after the previous
change.

	Fix it by simplifying the checks in ip_route_me_harder
and use FLOWI_FLAG_ANYSRC even for sockets. It looks safe
because the initial routing allowed this source address to
be used and now we just have to make sure the packet is rerouted.

	As a side effect this also allows rerouting for normal
raw sockets that use spoofed source addresses which was not possible
even before we eliminated the ip_route_input call.

Currently userland will barf when including linux/netlink.h unless it
precisely includes sys/socket.h first.  The issue is where the
definition of "sa_family_t" comes from.

We've been back and forth on how to fix this issue in the past, see:

http://thread.gmane.org/gmane.linux.debian.devel.bugs.general/622621
http://thread.gmane.org/gmane.linux.network/143380

Ben Hutchings suggested we take a hint from how we handle the
sockaddr_storage type.  First we define a "__kernel_sa_family_t"
to linux/socket.h that is always defined.

Then if __KERNEL__ is defined, we also define "sa_family_t" as
equal to "__kernel_sa_family_t".

Then in places like linux/netlink.h we use __kernel_sa_family_t
in user visible datastructures.
