We are using the VLAN_TAG_PRESENT bit to detect whether the PVID is
set or not at br_get_pvid(), while we don't care about the bit in
adding/deleting the PVID, which makes it impossible to forward any
incomming untagged frame with vlan_filtering enabled.
Since vid 0 cannot be used for the PVID, we can use vid 0 to indicate
that the PVID is not set, which is slightly more efficient than using
the VLAN_TAG_PRESENT.
Fix the problem by getting rid of using the VLAN_TAG_PRESENT.

"This is the first NFC pull request for the 3.13 kernel.
It's a fairly big one, with the following highlights:
- NFC digital layer implementation: Most NFC chipsets implement the NFC
digital layer in firmware, but others have more basic functionalities
and expect the host to implement the digital layer. This layer sits
below the NFC core.
- Sony's port100 support: This is "soft" NFC USB dongle that expects the
digital layer to be implemented on the host. This is the first user of
our NFC digital stack implementation.
- Secure element API: We now provide a netlink API for enabling,
disabling and discovering NFC attached (embedded or UICC ones) secure
elements. With some userspace help, this allows us to support NFC
payments.
Only the pn544 driver currently supports that API.
- NCI SPI fixes and improvements: In order to support NCI devices over
SPI, we fixed and improved our NCI/SPI implementation. The currently
most deployed NFC NCI chipset, Broadcom's bcm2079x, supports that mode
and we're planning to use our NCI/SPI framework to implement a
driver for it.
- pn533 fragmentation support in target mode: This was the only missing
feature from our pn533 impementation. We now support fragmentation in
both Tx and Rx modes, in target mode."

link_cmd_set_value() takes commands for link, bearer and media related
configuration. Genereally the function returns 0 when a command is
recognized, and -EINVAL when it is not. However, in the switch for link
related commands it returns 0 even when the command is unrecognized. This
will sometimes make it look as if a failed configuration command has been
successful, but has otherwise no negative effects.
We remove this anomaly by returning -EINVAL even for link commands. We also
rework all three switches to make them conforming to common kernel coding
style.

Currently, rcv_msg() always returns zero on a packet delivery upcall
from net_device.
To make its behavior more compliant with the way this API should be
used, we change this to let it return NET_RX_SUCCESS (which is zero
anyway) when it is able to handle the packet, and NET_RX_DROP otherwise.
The latter does not imply any functional change, it only enables the
driver to keep more accurate statistics about the fate of delivered

as argument. This requires the function to make a lookup to find
the pointer to the corresponding bearer struct. In the current
code base this is not necessary, since the only two callers

copies of this pointer, and hence can pass it directly in the
function call.

TIPC 'bearer' exists as an abstract concept, while 'media'
is deemed a specific implementation of a bearer, such as Ethernet
or Infiniband media. When a component inside TIPC wants to control
a specific media, it only needs to access the generic bearer API
to achieve this. However, in the current media implementations,
the 'bearer' name is also extensively used in media specific
function and variable names.
This may create confusion, so we choose to replace the term 'bearer'
with 'media' in all function names, variable names, and prefixes
where this is what really is meant.
Note that this change is cosmetic only, and no runtime behaviour
changes are made here.

tipc_msg_build() calls skb_copy_to_linear_data_offset() to copy data

in its turn call memcpy() to perform the actual copying. This poses
an obvious security and robustness risk, since memcpy() never makes
any validity check on the pointer it is copying from.
