When sending skbs, qeth determines the number of qdio SBAL elements
required. If qeth sends a fragmented skb, the SBAL element number
calculation is wrong, because the fragmented data part is added
twice in qeth_l3_tso_elements(). This patch makes sure fragmented
data is handled in qeth_elements_for_frags() only, while
qeth_l3_tso_elements() starts calculation of qdio SBAL elements just
with the linear data part of the skb.

/sys/class/net/<interface>/operstate for an active qeth network
interface offen shows "unknown", which translates to "state UNKNOWN
in output of "ip link show". It is caused by a missing initialization

When the linear buffer of the received sk_buff is shorter than
the header, use skb_linearize(). sk_buffs with short linear buffer
happen on the sending side under high traffic, and some kernel
configurations, when allocated buffer starts just before page
boundary, and IUCV transport has to send it as two separate QDIO
buffer elements, with fist element shorter than the header.

This patch removes ARPHRD_IEEE802154 from addrconf handling. In the
earlier days of 802.15.4 6LoWPAN, the interface type was ARPHRD_IEEE802154
which introduced several issues, because 802.15.4 interfaces used the
same type.
Since commit 965e613d299c ("ieee802154: 6lowpan: fix ARPHRD to
ARPHRD_6LOWPAN") we use ARPHRD_6LOWPAN for 6LoWPAN interfaces. This
patch will remove ARPHRD_IEEE802154 which is currently deadcode, because
ARPHRD_IEEE802154 doesn't reach the minimum 1280 MTU of IPv6.
Also we use 6LoWPAN EUI64 specific defines instead using link-layer
constanst from 802.15.4 link-layer header.

100GbE Intel Wired LAN Driver Updates 2015-12-13
This series contains updates to fm10k only.
Jacob updates the driver to use ether_addr_copy() instead of copying
byte-by-byte in a for loop. Fixed up CamelCase variable names and coding
style issues. Cleaned up namespace pollution of fm10k_iov_msg_data_pf().
Cleaned up, by making it consistent, the use of VLAN and VLAN ID instead of
vlan or vid. Lastly, update the driver to initialize XPS so that we can
take advantage of the kernel feature.
Alex Duyck fixed up the driver to free the resources associated with the
MSI-X vector table if the q_vector allocation failed. Then fixed the driver
to check for msix_entries to be NULL and freed the IRQ if the mailbox API
returned an error on trying to connect.
Bruce cleans up whitespace and namespace pollution issues in the driver.
Also updates the driver to use the BIT() macro instead of bit-shifting coding.

This patch addresses two issues.
First is the fact that the fm10k_mbx_free_irq was assuming msix_entries was
valid and that will not always be the case. As such we need to add a check
for if it is NULL.
Second is the fact that we weren't freeing the IRQ if the mailbox API
returned an error on trying to connect.

====================
1GbE Intel Wired LAN Driver Updates 2015-12-12
This series contains updates to e1000, e1000e and igb.
Joern Engel fixes up the e1000 driver to reduce scheduler latencies by
making the eeprom read/write functions scheduler friendly by using a mutex
lock instead of a spin lock.
Todd adds code for igb to initialize the 88E1543 PHY properly. Then fixed
igb to use the correct i210 register for EEMNGCTL, since the i210 has two
EEPROM access registers (EEARBC and EEMNGCTL).
Dmitry Vyukov provides a fix for e1000 to resolve a data race found with
KernelThreadSanitizer (KTSAN), where no memory barriers were being used
when buffers get recycled, so the recycled buffers can be corrupted. So
use smp_store_release() to update tx_ring->next_to_clean and
smp_load_acquire() to read tx_ring->next_to_clean to properly hand off
buffers from e1000_clean_tx_irq() to e1000_xmit_frame().
Jarod Wilson fixes igb so that we do not try to unmap a NULL hw_addr. Then
cleaned up array_rd32() so that it uses igb_rd32() the same as rd32() and
use io_addr() in more places so that we do not have to call E1000_REMOVED().
Janusz Wolak cleans up the e1000 driver by correcting warnings produced
by checkpatch.pl for the driver.
Jean Sacren provides several patches with general cleanups for e1000 and
e1000e, which include code comment fix-ups and cleanup of local variables
not needed.
Dmitry Fleytman fixes a possible division by zero in the receive interrupt
handler for e1000e when working without adaptive interrupt moderation,
which is typically disabled on jumbo MTUs.
Raanan increases the timeout of the polling bit due to timing changes to
the ME firmware on a platform, so increase the timeout to 300ms. Added
initial support for i219-LM, which is a LOM that will be available on
systems with the Lewisburg Platform Controller HUB (PCH) chipset.
Jan Beulich fixes a NULL dereference in igb, due to the adapter->vf _data
being NULL while adapter->vfs_allocated_count is non-zero.

40GbE Intel Wired LAN Driver Updates 2015-12-12
This series contains updates to i40e and i40evf only.
Jesse fixes some trivial static analyzer warnings where BIT() can be used
instead of BIT_ULL().
Mitch fixes the virtual channel interface which was using incorrect semantics
to remove MAC addresses and would leave incorrect filters active when using
VLANs. Also fixes an issue that when VF's are created, the MAC address
defaults to all zeros, indicating to the VF driver that it should use a
random MAC address. However, the PF driver was incorrectly adding this
zero MAC to the filter table, so check for a good address before adding
the default filter. Adds a check to make sure that the Tx and Rx rings
actually exist before dereferencing them to free resources. Re-classifies
several messages which are really for debugging purposes, especially since
the driver can fully recover from any of these. Fixed up the VF version
strings to match the PF driver.
Anjali adds a virtchnl offload to support the expanded version of TCP/UDP
PCTYPES for RSS.
Shannon fixes i40e to clean the whole MAC filter list when resetting after
an intermediate add or delete push to the firmware.

The combined effect of commits 6423fc3416 ("igb: do not re-init SR-IOV
during probe") and ceee3450b3 ("igb: make sure SR-IOV init uses the
right number of queues") causes VFs no longer getting set up, leading
to NULL pointer dereferences due to the adapter's ->vf_data being NULL
while ->vfs_allocated_count is non-zero. The first commit not only
neglected the side effect of igb_sriov_reinit() that the second commit
tried to account for, but also that of setting IGB_FLAG_HAS_MSIX,
without which igb_enable_sriov() is effectively a no-op. Calling
igb_{,re}set_interrupt_capability() as done here seems to address this,
but I'm not sure whether this is better than sinply reverting the other
two commits.

The checking logic needed some clean-up work, so we rewrite it by
checking for break first. With that change in place, we can even move
the second check for goto statement outside of the loop.
As this is merely a cleanup, no functional change is involved. The
questionable 'tmp != 0xFF' is intentionally left alone.
