The patch provides USB CDC NCM host driver support in the Linux Kernel.

Changes:
drivers/net/usb/cdc_ncm.c:
- initial submission of the CDC NCM host driver;
- verified on Intel 32/64 bit, Intel Atom, ST-Ericsson U8500 (ARM)
- throughput measured over 100 Mbits duplex;
- driver supports 16-bit NTB format only, but it is more than enough for
  transfers up to 64K;
- driver can handle up to 32 datagrams in received NTB;
- timer is used to collect several packets in Tx direction

drivers/net/usb/Kconfig:
- a new entry to compile CDC NCM host driver
drivers/net/usb/Makefile:
- a new entry to compile CDC NCM host driver

Changes:
include/linux/usb/usbnet.h:
- a new flag to indicate driver's capability to accumulate IP packets in Tx
 direction and extract several packets from single skb in Rx direction.
drivers/net/usb/usbnet.c:
- the procedure of counting packets in usbnet was updated due to the
 accumulating of IP packets in the driver
- no short packets are sent if indicated by the flag in driver_info
 structure

The first hunk of this patch makes sure that the driver checks for the
appropriate preconditions before checking if EEE negotiation succeeded.
More specifically the link needs to be full duplex for EEE to be
enabled.

The second and third hunks of this patch fix a bug where the eee
advertisement register would be programmed with extra bits set.

The fourth hunk of this patch makes sure the EEE capability flag is not
set for 5718 A0 devices and that the device is not a serdes device.

None of these modifications are strictly necessary.  The driver /
hardware still does the right thing.  They are submitted primarily for
correctness.

The mcfw *never* sends CMDDONE when rebooting. Changing this so that it always
sends CMDDONE *before* REBOOT is easy on Siena, but it's not obvious that we
could guarantee to be able to implement this on future hardware.

Given this, I'm less convinced that the protocol should be changed.

To reiterate the failure mode: The driver sees this:

 issue command
 receive REBOOT event

Was that reboot event sent before the command was issued, or in
response to the command? If the former then there will be a subsequent
CMDDONE event, if the latter, then there will be no CMDDONE event.

Options to resolve this are:

 1. REBOOT always completes an outstanding mcdi request, and we set
    the credits count to ignore a subsequent CMDDONE event with
    mismatching seqno.

 2. REBOOT never completes an outstanding mcdi request. If there is
    no CMDDONE event then we rely on the mcdi timeout code to complete
    the outstanding request, incurring a 10s delay.

I'd argue that (2) is tidier, but that incurring a 10s delay is a little
needless. Let's go with (1).

Moves the content of each native API message forwarding routine
into the sole routine that calls it, since the forwarding routines
no longer be called in isolation. Also removes code in each routine
that altered the outgoing message's importance level since this is
now no longer possible.

The previous function mapping (parent function, and child API) was
as follows:

   tipc_send2name
       \--tipc_forward2name

   tipc_send2port
       \--tipc_forward2port

   tipc_send_buf2port
       \--tipc_forward_buf2port

After this commit, the children don't exist and their functionality
is completely in the respective parent.
