Hardware encryption seems to break encrypted unicast mgmt tx.
Unfortunately the hardware TXWI header does not have a bit to indicate
that a frame is software encrypted, so sw-encrypted frames need to use a
different WCID. For that to work, the CCMP PN needs to be generated in
software, which makes things a bit slower, so only do it for keys that
also need to tx management frames.

mlx5-updates-2018-01-19

From: Or Gerlitz <ogerlitz@mellanox.com>
=======
First six patches of this series further enhances the mlx5 hairpin support.
The first two patches deal with using different hairpin instances
for flows whose packets have different priorities to align with the port
TX QoS model. The next four patches allow us to do HW spreading
of flows over a set of hairpin pairs using RSS. The last two patches
change the driver to also set the size of the HW hairpin queues.
========

Next four patches from Eran Ben Elisha <eranbe@mellanox.com>:
Add more debug data for TX timeout handling, and further enhance and optimize
TX timeout handling upon lost interrupts, which adds a mechanism for explicitly
polling EQ in case of a TX timeout in order to recover from a lost interrupt.
If this is not the case (no pending EQEs), perform a channels full recovery as
usual.

From Kamal Heib <kamalh@mellanox.com>, Two patches to extend the stats group API
to have an update_stats() callback which will be used to fetch the hardware or
software counters data, this will improve the current API and reduce code
duplication.

Previously it was possible to interrupt processing stats updates because

Netfilter/IPVS updates for net-next

The following patchset contains Netfilter/IPVS updates for your net-next
tree. Basically, a new extension for ip6tables, simplification work of
nf_tables that saves us 500 LoC, allow raw table registration before
defragmentation, conversion of the SNMP helper to use the ASN.1 code
generator, unique 64-bit handle for all nf_tables objects and fixes to
address fallout from previous nf-next batch.  More specifically, they
are:

1) Seven patches to remove family abstraction layer (struct nft_af_info)
   in nf_tables, this simplifies our codebase and it saves us 64 bytes per
   net namespace.

2) Add IPv6 segment routing header matching for ip6tables, from Ahmed
   Abdelsalam.

3) Allow to register iptable_raw table before defragmentation, some
   people do not want to waste cycles on defragmenting traffic that is
   going to be dropped, hence add a new module parameter to enable this
   behaviour in iptables and ip6tables. From Subash Abhinov
   Kasiviswanathan. This patch needed a couple of follow up patches to
   get things tidy from Arnd Bergmann.

4) SNMP helper uses the ASN.1 code generator, from Taehee Yoo. Several
   patches for this helper to prepare this change are also part of this
   patch series.

5) Add 64-bit handles to uniquely objects in nf_tables, from Harsha
   Sharma.

6) Remove log message that several netfilter subsystems print at
   boot/load time.

7) Restore x_tables module autoloading, that got broken in a previous
   patch to allow singleton NAT hook callback registration per hook
   spot, from Florian Westphal. Moreover, return EBUSY to report that
   the singleton NAT hook slot is already in instead.

8) Several fixes for the new nf_tables flowtable representation,
   including incorrect error check after nf_tables_flowtable_lookup(),
   missing Kconfig dependencies that lead to build breakage and missing
   initialization of priority and hooknum in flowtable object.

9) Missing NETFILTER_FAMILY_ARP dependency in Kconfig for the clusterip
   target. This is due to recent updates in the core to shrink the hook
   array size and compile it out if no specific family is enabled via
   .config file. Patch from Florian Westphal.

10) Remove duplicated include header files, from Wei Yongjun.

11) Sparse warning fix for the NFPROTO_INET handling from the core
    due to missing static function definition, also from Wei Yongjun.

12) Restore ICMPv6 Parameter Problem error reporting when
    defragmentation fails, from Subash Abhinov Kasiviswanathan.

13) Remove obsolete owner field initialization from struct
    file_operations, patch from Alexey Dobriyan.

14) Use boolean datatype where needed in the Netfilter codebase, from
    Gustavo A. R. Silva.

15) Remove double semicolon in dynset nf_tables expression, from
    Luis de Bethencourt.
