Re-submitted based on comments from netdev community.
Summary of the changes:
1. Improved error handling.
2. Added the missing timeout arguments to usb_control_msg().

The following is a new Linux driver which exposes certain models of Sierra
Wireless modems to the operating system as Network Interface Cards (NICs).

This driver requires a version of the sierra.c driver which supports
blacklisting to work properly. The blacklist in sierra.c rejects the interfaces
claimed by sierra_net.c. Likewise, the sierra_net.c driver only accepts
(i.e. whitelists) the interface(s) used for USB-to-WWAN traffic.
The version of sierra.c which supports blacklisting is
available from the sierra wireless knowledge base page for older kernels. It is
also available in Linux kernel starting from version 2.6.31.

This driver works with all Sierra Wireless devices configured with PID=68A3
like USB305, USB306 provided the corresponding firmware version is I2.0
(for USB305) or M3.0 (for USB306) and later.
This driver will not work with earlier firmware versions than the ones shown
above. In this case the driver will issue an error message indicating
incompatibility and will not serve the device's USB-to-WWAN interface.

Sierra_net.c sits atop a pre-existing Linux driver called usbnet.c.
A series of hook functions are provided in sierra_net.c which are called by
usbnet.c in response to a particular condition such as receipt or transmission
of a data packet. As such, usbnet.c does most of the work of making
a modem appear to the system as a network device and for properly exchanging
traffic between the USB subsystem and the Network card interface.
Sierra_net.c is concerned with managing the data exchanged between the
USB-to-WWAN interface and the upper layers of the operating system.

The bonding driver calls ndo_vlan_rx_register() while holding bond->lock.
The bnx2 driver calls bnx2_netif_stop() to stop the rx handling while
changing the vlgrp.  The call also stops the cnic driver which sleeps
while the bond->lock is held and cause the warning.

This code path only needs to stop the NAPI rx handling while we are
changing the vlgrp.  Since no reset is going to occur, there is no need
to stop cnic in this case.  By adding a parameter to bnx2_netif_stop()
to skip stopping cnic, we can avoid the warning.

It has been reported that under certain heavy traffic conditions in MSI-X
mode, the driver can lose an MSI-X vector causing all packets in the
associated rx/tx ring pair to be dropped.  The problem is caused by
the chip dropping the write to unmask the MSI-X vector by the kernel
(when migrating the IRQ for example).

This can be prevented by increasing the GRC timeout value for these
register read and write operations.

Prompted by a previous patch submitted by Matthew Garret <mjg@redhat.com>,
further digging into errata documentation reveals the current enabling or
disabling of ASPM L0s and L1 states for certain parts supported by this
driver are incorrect.  82571 and 82572 should always disable L1.  For
standard frames, 82573/82574/82583 can enable L1 but L0s must be disabled,
and for jumbo frames 82573/82574 must disable L1.  This allows for some
parts to enable L1 in certain configurations leading to better power
savings.

Also according to the same errata, Early Receive (ERT) should be disabled
on 82573 when using jumbo frames.

Port autoselection done by kernel only works when number of bound

When this threshold is over, we must check if there is a conflict before
exiting first loop in inet_csk_get_port()

The issue raises when having 2 NICs both assigned the same
IPv6 global address.

If a sender binds to a particular NIC (SO_BINDTODEVICE),
the outgoing traffic is being sent via the first found.
The bonded device is thus not taken into an account during the
routing.

From the ip6_route_output function:

If the binding address is multicast, linklocal or loopback,
the RT6_LOOKUP_F_IFACE bit is set, but not for global address.

So binding global address will neglect SO_BINDTODEVICE-binded device,
because the fib6_rule_lookup function path won't check for the
flowi::oif field and take first route that fits.

After receiving a ICMPv6 Too Big message reporting PMTU is
less than the IPv6 Minimum Link MTU, sctp *can't* send any
data/control chunk that total length including IPv6 head
and IPv6 extend head is less than IPV6_MIN_MTU(1280 bytes).

The failure occured in p6_fragment(), about reason
see following(take SHUTDOWN chunk for example):
sctp_packet_transmit (SHUTDOWN chunk, len=16 byte)
|------sctp_v6_xmit (local_df=0)
   |------ip6_xmit
       |------ip6_output (dst_allfrag is ture)
           |------ip6_fragment

In ip6_fragment(), for local_df=0, drops the the packet
and returns EMSGSIZE.

The patch fixes it with adding check length of skb->len.
In this case, Ipv6 not to fragment upper protocol data,
just only add a fragment header before it.

Add new driver to use tethering with an iPhone device. After initial submission,
apply fixes to fit the new driver into the kernel standards.

There are still a couple of minor (almost cosmetic-level) issues, but the driver
is fully functional right now.

I encountered an issue that not to link up on cxgb3 fabric.
I bisected and found that this regression was introduced by

Correct to pass phy_addr to cphy_init() at t3_xaui_direct_phy_prep().

1, An X25 program binds and listens
2, calls arrive waiting to be accepted
3, Program exits without accepting
4, Sockets time out but don't get correctly cleaned up
5, cat /proc/net/x25/socket shows the dead sockets with bad inode fields.

This line borrowed from AX25 sets the dying socket so the timers clean up later.

Update the stats counter calculation in 3c574_cs, similar
to the method used in 3c589_cs. This corrects the contents
of the counter on tests using a "Megahertz 574B" card.

In ems_usb_probe(), a pointer is dereferenced after making sure it is NULL...

This patch replaces netdev->dev.parent with &intf->dev in dev_err() calls to
avoid this.
