MVNETA_BM has a dependency on MVNETA, so we can only select the former

The mvneta module can call into the mvneta_bm module, so mvneta cannot
be a built-in if mvneta_bm is a module, or we get a link error:

This avoids the problem by further clarifying the dependency so that

There are two issues with the current code. First one is that we need
to set res->class to 0 in case we use non-default classid matching.

This is important for the case where cls_bpf was initially set up with
an optional binding to a default class with tcf_bind_filter(), where
the underlying qdisc implements bind_tcf() that fills res->class and
tests for it later on when doing the classification. Convention for
these cases is that after tc_classify() was called, such qdiscs (atm,
drr, qfq, cbq, hfsc, htb) first test class, and if 0, then they lookup
based on classid.

Second, there's a bug with da mode, where res->classid is only assigned
a 16 bit minor, but it needs to expand to the full 32 bit major/minor
combination instead, therefore we need to expand with the bound major.
This is fine as classes belonging to a classful qdisc must share the
same major.

ldmvsw: Add ldmvsw driver

This series adds a new Logical Domains vSwitch (ldmvsw) driver.

The ldmvsw driver code will live in the drivers/net/ethernet/sun/
directory and will operate on Oracle systems running SPARC Linux in a
Logical Domains environment (typically in the control domain).

The ldmvsw driver is very similar in function to the existing sunvnet
driver. Ldmvsw creates a network interface for each "vsw-port" node
found in the Machine Description (MD) of a service domain. These
nodes correspond to ports on a vswitch created by the logical domains
manager. The created network interface(s) can be used by bridge/vswitch
software (such as the Linux bridge or Open vSwitch) to provide
guest domain(s) with network interconnectivity or connectivity
to a physical network.

Here is a example diagram of ldmvsw driver usage in a logical
domain environment to provide a guest domain with network connectivity
to a physical NIC on the service domain:

   +----------------+             +-----------------
   | Service Domain |             |  Guest domain  |
   |                |             |                |
   |  LinuxBridge   |             |                |
   |    |    |      |             |                |
   |   NIC Ldmvsw   |             |    Sunvnet     |
   +----------------+             +----------------+
        |    |           LDC              |
       LAN   ------------------------------

As stated, the sunvnet and ldmvsw drivers are _very_ similar in function.
They both create network interface(s) to receive/transmit network
traffic across LDC network channel(s). Since the driver is so similar
in function to sunvnet, the approach will be as follows to integrate
the driver and take advantage of common code:

Patch #1: Split sunvnet.c driver into sunvnet.c and sunvnet_common.c
Patch #2: Modify the sunvnet_common code and data structures to be compatible
          with both the sunvnet and ldmvsw drivers.
Patch #3: Add the new ldmvsw.c driver code
Patch #4: Checkpatch cleanup of the sunvnet/sunvnet_common code.

NOTE - Patch#1 renames a file (sunvnet.h -> sunvnet_common.h). When generating
the patches (using git format-patch), I had to use the --no-renames option
otherwise patch#1 would NOT apply using 'patch -p1' - which as I
understand is a requirement for patch acceptance. I wasn't sure if this
is proper thing to do.  Please advise if not. Thanks.

v2 changes:
  * change all EXPORT_SYMBOL declarations to EXPORT_SYMBOL_GPL
  * remove inline attribute for external function port_is_up_common()
  * Give all exported/global funcs in sunvnet_common.c a 'sunvnet_' prefix
    to avoid kernel global namespace pollution/collisions
  * ldmvsw.c: Order local variable declarations from longest to shortest line
  * ldmvsw.c: register the netdevice after all supporting state is ready/setup.
              NOTE: The consensus at Oracle is that the following functions
                    must be done AFTER register_netdev() - this is the same
                    ordering currently used in the sunvnet driver:
                    1. sunvnet_port_add_txq_common() - needs registered netdev
                    2. napi_enable() - requires registered netdev
                    3. vio_port_up() - as soon as this function is called
                                       LDC handshake messages will come in
                                       which must be handled by the napi code.

  Add ldmvsw.c driver

  Details:

  The ldmvsw driver very closely follows the sunvnet.c code and makes
  use of the sunvnet_common.c code for core functionality.

  A significant difference between sunvnet and ldmvsw driver is
  sunvnet creates a network interface for each vnet-port *parent*
  node in the MD while the ldmvsw driver creates a network interface
  for every vsw-port node in the Machine Description (MD).
  Therefore the netdev_priv() for sunvnet is a vnet structure while
  the netdev_priv() for ldmvsw is a vnet_port structure.

  Vnet_port structures allocated by ldmvsw have the vsw bit set.
  When finding the net_device associated with a port, the common code keys
  off this bit to use either the net_device found in the vnet_port or the
  net_device in the vnet structure (see the VNET_PORT_TO_NET_DEVICE() macro in
  sunvnet_common.h). This scheme allows the common code to work with
  both drivers with minimal changes.

  Similar to Xen, network interfaces created by the ldmvsw driver will always
  have a HW Addr (i.e. mac address) of FE:FF:FF:FF:FF:FF and each will be
  assigned the devname "vif<cfg_handle>.<port_id>" - where <cfg_handle> and
  <port_id> are a unique handle/port pair assigned to the associated
  vsw-port node in the MD.

  Modify sunvnet common code and data structures to be compatible
  with both sunvnet and ldmvsw drivers.

  Details:

  Sunvnet operates on "vnet-port" nodes which appear in the Machine
  Description (MD) in a guest domain. Ldmvsw operates on "vsw-port"
  nodes which appear in the MD of a service domain.

  A difference between the sunvnet driver and the ldmvsw driver is
  the sunvnet driver creates a network interface (i.e. a struct net_device)
  for every vnet-port *parent* "network" node. Several vnet-ports may appear
  under this common parent network node - each corresponding to a common parent
  network interface.  Conversely, since bridge/vswitch software will need
  to interface with every vsw-port in a system, the ldmvsw driver creates
  a network interface (i.e. a struct net_device) for every vsw-port - not
  every parent node as with sunvnet.  This difference required some special
  handling in the common code as explained below.

  There are 2 key data structures used by the sunvnet and ldmvsw drivers
  (which are now found in sunvnet_common.h):

  1. struct vnet_port
     This structure represents a vnet-port node in sunvnet and a vsw-port
     in the ldmvsw driver.

  2. struct vnet
     This structure represents a parent "network" node in sunvnet and a parent
     "virtual-network-switch" node in ldmvsw.

  Since the sunvnet driver allocates a net_device for every parent "network"
  node, a net_device member appears in the struct vnet. Since the ldmvsw
  driver allocates a net_device for every port, a net_device member was
  added to the vnet_port. The common code distinguishes which structure
  net_device member to use by checking a 'vsw' bit that was added to the
  vnet_port structure. See the VNET_PORT_TO_NET_DEVICE() marco in
  sunvnet_common.h.

  The netdev_priv() in sunvnet is allocated as a vnet. The netdev_priv()
  in ldmvsw is a vnet_port. Therefore, any place in the common code
  where a netdev_priv() call was made, a wrapper function was implemented
  in each driver to first get the vnet and/or vnet_port (in a driver
  specific way) and pass them as newly added parameters to the common
  functions (see wrapper funcs: vnet_set_rx_mode() and vnet_poll_controller()).
  Since these wrapper functions call __tx_port_find(), __tx_port_find() was
  moved from the common code back into sunvnet.c. Note - ldmvsw.c does not
  require this function.

  These changes also required that port_is_up() be made
  into a common function and thus it was given a _common suffix and
  exported like the other common functions.

  A wrapper function was also added for vnet_start_xmit_common() to pass a
  driver-specific function arg to return the port associated with a given
  struct sk_buff and struct net_device. This was required because
  vnet_start_xmit_common() grabs a lock prior to getting the associated
  port. Using a function pointer arg allowed the code to work unchanged
  without risking changes to the non-trivial locking logic in
  vnet_start_xmit_common().

  Split sunvnet.c into sunvnet.c and sunvnet_common.c.

  Details:

  Since the sunvnet and ldmvsw drivers will both use common sunvnet code,
  move the functions (and support functions) anticipated to be common code
  from sunvnet.c to sunvnet_common.c. Similarly, sunvnet.h was renamed to
  sunvnet_common.h. The sunvnet_common.c code will be compiled into the
  kernel and act as a library of functions that are linked by either
  (or both) drivers when loaded.

  Function names for external functions in sunvnet_common.c (to be
  called by both the sunvnet and ldmvsw drivers) were tagged with a "_common"
  suffix to clearly designate them as common functions.

  No functional changes as of yet... just moved code verbatim to the new
  sunvnet_common.c/h files.

  Makefile/Kconfig support added to build sunvnet_common.c file. The code
  is included in the kernel if SUN_LDOMS is defined/selected.

  NOTE - per the SubmittingPatches documentation, since the code was just
  moved from one file another, the code was NOT checkpatch'd in this commit
  to aid in review.

Currently output of MPLS packets on tunnel vports is not allowed by Open
vSwitch. This is because historically encapsulation was done in such a way
that the inner_protocol field of the skb needed to hold the inner protocol
for both MPLS and tunnel encapsulation in order for GSO segmentation to be
performed correctly.

Since b2acd1dc ("openvswitch: Use regular GRE net_device instead of
vport") Open vSwitch makes use of lwt to output to tunnel netdevs which
perform encapsulation. As no drivers expose support for MPLS offloads this
means that GSO packets are segmented in software by validate_xmit_skb(),
which is called from __dev_queue_xmit(), before tunnel encapsulation occurs.
This means that the inner protocol of MPLS is no longer needed by the time
encapsulation occurs and the contention on the inner_protocol field of the
skb no longer occurs.

Thus it is now safe to output MPLS to tunnel vports.

obtained, but will be unused due to returning -EPROBE_DEFER.

Also, since we can break out of the probing loop early, we need to
explicitly call of_node_put() outside of the loop.
