====================
NFC 4.3 pull request
This is the NFC pull request for 4.3.
With this one we have:
- A new driver for Samsung's S3FWRN5 NFC chipset. In order to
properly support this driver, a few NCI core routines needed
to be exported. Future drivers like Intel's Fields Peak will
benefit from this.
- SPI support as a physical transport for STM st21nfcb.
- An additional netlink API for sending replies back to userspace
from vendor commands.
- 2 small fixes for TI's trf7970a
- A few st-nci fixes.

The current Secure port mode requires the port-based VLANs to also be
valid in the 802.1Q VLAN Table Unit. The current hardware bridging
support only configures the port-based VLANs, thus is broken.
A new patchset is required to adapt the hardware bridging code to fully
support the Secure port mode.
In the meantime, change the 802.1Q mode of every ports to Fallback,
which filtering is more permissive, and doesn't add this restriction to
handle port-based and tagged-based VLANs.

Currently, the lwtunnel state resides in per-protocol data. This is
a problem if we encapsulate ipv6 traffic in an ipv4 tunnel (or vice versa).
The xmit function of the tunnel does not know whether the packet has been
routed to it by ipv4 or ipv6, yet it needs the lwtstate data. Moving the
lwtstate data to dst_entry makes such inter-protocol tunneling possible.
As a bonus, this brings a nice diffstat.

REPORT LUNS should not fail just because the allocation length is less

4.2.5.6 Allocation length
The ALLOCATION LENGTH field specifies the maximum number of bytes or
blocks that an application client has allocated in the Data-In
Buffer. The ALLOCATION LENGTH field specifies bytes unless a
different requirement is stated in the command definition.
An allocation length of zero specifies that no data shall be
transferred. This condition shall not be considered an error.

====================
Intel Wired LAN Driver Updates 2015-08-18
This series contains updates to igb, e100, e1000e and ixgbe.
Shota Suzuki provides a fix for a possible overflow in
igb_set_interrupt_capability() which leads to an oops. When changing the
number of queues by "ethtool -L", set IGB_FLAG_QUEUE_PAIRS in the same
manner as when initializing the igb driver.
Vasily Averin provides a fix for a missing rtnl_unlock() for when we
error out due to not being able to allocate memory for our queues.
Stefan Assman provides a couple of fixes for igb/igbvf. First changes
the igb driver in probe to simply call igb_enable_sriov() instead of
igb_sriov_reinit() since we are starting from scratch. Then in igbvf,
fix the driver where it does not clear the buffer_info->dma in all
cases after calling dma_unmap_single(), which was found by changing the
MTU twice.
Richard Cochran implements the periodic output function using the
programmable clock outputs available in i210 when possible, falling
back to the target time for longer periods.
Todd adds support for the Marvell PHY 1512 which is required for i354
devices. Then updates igb to make sure SR-IOV init uses the correct
number of queues, since recent changes could result in the PF holding
onto all of the queues.
Alex Williamson provides a fix in the case where a guest OS does not
support hot-unplug, so disable SR-IOV prior to unregister_netdev() to
avoid the problem.
Jia-Ju Bai provides several patches, first knocks some collecting dust
off an old e100 driver to add a check to avoid a null pointer
dereference. Then cleans up a possible resource leak by releasing the
skb buffer allocated when the e100_xmit_prepare() runs into an issue
in the DMA mapping. In igb, add a missing rtnl_unlock() for when we
error out due to igb_sriov_reinit() in the igb_init_interrupt_scheme().
Provides a e1000e fix, based on suggestions from Alex Duyck to move
head/tail register writing to e1000_configure_tx/rx() to avoid a
possible null pointer dereference (similar to igb driver). Lastly,
fix a possible memory leak in igb_probe(), where the memory shadow_vfta
allocated by kcalloc in igb_sw_init() is not freed.
Mark simplifies port-specific macros for ixgbe by eliminating explicit
comparisons with 0 and enclose formal parameters in parens to eliminate
the risk of an operator precedence issue.
