Different net namespaces might have different requirements as to

mlxsw: Adding layer 2 multicast
Elad says:
This patchset add Linux hardware reflection for L2 multicast offload and add
MC support in mlxsw. For every bridge MDB entry insertion, either by IGMP
snooping or by static insertion/removal, a switchdev ops is been called.
In mlxsw, a new multicast group (MID) is been created and ports are assigned.
When all ports are removed, the multicast group is been deleted.

It may happen that we get notification for FDB entry for object (port,

2) Destroy basechain and rules on netdevice removal in the new netdev
family.
3) Get rid of defensive check against removal of inactive objects in

4) Pass down netns pointer to our existing nfnetlink callbacks, as well
as commit() and abort() nfnetlink callbacks.
5) Allow to invert limit expression in nf_tables, so we can throttle
overlimit traffic.
6) Add packet duplication for the netdev family.
7) Add forward expression for the netdev family.
8) Define pr_fmt() in conntrack helpers.
9) Don't leave nfqueue configuration on inconsistent state in case of

10GbE Intel Wired LAN Driver Updates 2016-01-08
This series contains updates to ixgbe only.
Vasu provides three fixes for ixgbe, first assigns a minimum credit to
a traffic class to resolve a Tx hang for CEE mode configuration. Second
fix changes the driver to use netdev->fcoe_ddp_xid instead of our local
IXGBE_FCOE_DDP_MAX, since it is correctly set for our different devices
and avoids a DDP skip error on X550. Lastly fix the PFC configuration
to include X550 devices.
Emil provides a fix for reporting the speed in ethtool by using the
stored value in out adapter structure. This is due to external drivers
may end up with unknown speed when calling ethtool_get_settings().
Mark fixes the handling of any outer UDP checksum, by passing the
skb up with CHECKSUM_NONE when an outer UDP checksum is set. This
will cause the stack to check the checksum, also do not increment an
error counter because we do not really know if there is an actual error.
Ixgbe ATR was not handling IPv6 extended headers, so ATR is not being
performed on such packets. Fix this by skipping extended headers
when they are present.
Usha fixes an issue with X550 and getting FDMI HBA attributes when
FCoE support is enabled.
Neerav fixes an issue for X550 when FCoE and SR-IOV are enabled, which
the hardware generates MDD events. Resolve this by setting the expected
values in the transmit context descriptors for FCoE/FIP frames and
adding a flush after writing the RDLEN register.

40GbE Intel Wired LAN Driver Updates 2016-01-08
This series contains updates to i40e and i40evf only.
Mitch adds a useful error message and return value when the VFs are being
reset, since there is a brief window of time when the VF cannot be
configured because they do not have a VSI to configure. Also made a driver
change to allow the user to specify a zero MAC address for VFs, which
causes the existing MAC address to be removed and allows the VF to use a
random address (like libvirt).
Sowmini Varadhan from Oracle adds similar functionality/fix to i40e that
was added to ixgbe earlier. The fix attempts to look up the MAC address
in the Open Firmware on systems that support it and use IDPROM on SPARC
if no OF address is found.
Anjali provides a fix the code path so that we do not call skb_set_hash()
if the feature is disabled.
Jesse removes a device ID that has never been productized and there are
no plans to use it, so just remove it.
