USB CDC NCM host driver

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

 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

8 years agosfc: Fix event based MCDI completion and MC REBOOT/CMDDONE ordering issue
Steve Hodgson [Thu, 2 Dec 2010 13:46:55 +0000]
sfc: Fix event based MCDI completion and MC REBOOT/CMDDONE ordering issue

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).

As part of the removal of TIPC's native API support it is no longer
necessary for TIPC to export symbols for routines that can be called
by kernel-based applications, nor for it to have header files that

TIPC and migrates the contents of each obsolete native API include
file into its corresponding non-native API equivalent.

The code which was migrated in this commit was migrated intact, in

sctp: kill unused macros in head file

1. SCTP_CMD_NUM_VERBS,SCTP_CMD_MAX
These two macros have never been used for several years since v2.6.12-rc2.

2.sctp_port_rover,sctp_port_alloc_lock
The commit 063930 abandoned global variables of port_rover and port_alloc_lock,
but still keep two macros to refer to them.
So, remove them now.

Ursula Braun [Fri, 26 Nov 2010 02:41:19 +0000]
qeth: enable interface setup if LAN is offline

Device initialization of a qeth device contains a STARTLAN step.
This step may fail, if cable is not yet plugged in. The qeth device
stays in state HARDSETUP until cable is plugged in. This prevents
further preparational initialization steps of the qeth device and
its network interface. This patch makes sure initialization of qeth
device continues, even though cable is not yet plugged in.
Once carrier is available, qeth is notified, triggers a recovery
which results in a working network interface.

The commit to convert to use the dev_pm_ops struct
introduces a bug. The shutdown flag is not yet used
because the hibernation on memory is done by using
