When adding or deleting a batch of entries, the kernel sends upto
TCA_ACT_MAX_PRIO entries in an event to user space. However it does not
consider that the action sizes may vary and require different skb sizes.
For example :
% cat tc-batch.sh
TC="sudo /mnt/iproute2.git/tc/tc"
$TC actions flush action gact
for i in `seq 1 $1`;
do
cmd="action pass index $i "
args=$args$cmd
done
$TC actions add $args
%
% ./tc-batch.sh 32
Error: Failed to fill netlink attributes while adding TC action.
We have an error talking to the kernel
%
This patchset introduces new callback in tc_action_ops, which calculates
the action size, and passes size to tcf_add_notify()/tcf_del_notify(). The
patch fixes act_gact, and the rest of actions will be updated in the
follow-up patches.
v3:
Fixed tcf_action_fill_size() to return shared attrs length when
action ->get_fill_size() isn't implemented.
v2:
Restructured patches to make them bisectable.

net: do not create fallback tunnels for non-default namespaces
fallback tunnels (like tunl0, gre0, gretap0, erspan0, sit0,
ip6tnl0, ip6gre0) are automatically created when the corresponding
module is loaded.
These tunnels are also automatically created when a new network
namespace is created, at a great cost.
In many cases, netns are used for isolation purposes, and these
extra network devices are a waste of resources. We are using
thousands of netns per host, and hit the netns creation/delete
bottleneck a lot. (Many thanks to Kirill for recent work on this)
Add a new sysctl so that we can opt-out from this automatic creation.
Note that these tunnels are still created for the initial namespace,
to be the least intrusive for typical setups.

Edward Cree says:
====================
ntuple filters with RSS
This series introduces the ability to mark an ethtool steering filter to use
RSS spreading, and the ability to create and configure multiple RSS contexts
with different indirection tables, hash keys, and hash fields.
An implementation for the sfc driver (for 7000-series and later SFC NICs) is
included in patch 2/2.
The anticipated use case of this feature is for steering traffic destined for
a container (or virtual machine) to the subset of CPUs on which processes in
the container (or the VM's vCPUs) are bound, while retaining the scalability
of RSS spreading from the viewpoint inside the container.
The use of both a base queue number (ring_cookie) and indirection table is
intended to allow re-use of a single RSS context to target multiple sets of
CPUs. For instance, if an 8-core system is hosting three containers on CPUs
[1,2], [3,4] and [6,7], then a single RSS context with an equal-weight [0,1]
indirection table could be used to target all three containers by setting
ring_cookie to 1, 3 and 6 on the respective filters.
v2: Initialised ctx in efx_ef10_filter_insert() to avoid (false positive) gcc
warning.

====================
mlx5-updates-2018-02-28-2 (IPSec-2)
This series follows our previous one to lay out the foundations for IPSec
in user-space and extend current kernel netdev IPSec support. As noted in
our previous pull request cover letter "mlx5-updates-2018-02-28-1 (IPSec-1)",
the IPSec mechanism will be supported through our flow steering mechanism.
Therefore, we need to change the initialization order. Furthermore, IPsec
is also supported in both egress and ingress. Since our current flow
steering is egress only, we add an empty (only implemented through FPGA
steering ops) egress namespace to handle that case. We also implement
the required flow steering callbacks and logic in our FPGA driver.
We extend the FPGA support for ESN and modifying a xfrm too. Therefore, we
add support for some new FPGA command interface that supports them. The
other required bits are added too. The new features and requirements are
advertised via cap bits.
Last but not least, we revise our driver's accel_esp API. This API will be
shared between our netdev and IB driver, so we need to have all the required
functionality from both worlds.

selftests/net: enable fragments for fib-onlink-tests
We miss CONFIG_* fragments so test fib-onlink-tests.sh can do:
ip li add lisa type vrf table 1101
ip li add veth1 type veth peer name veth2
And the follow message occurs if it isn't enabled:

RTNETLINK answers: Operation not supported
This enables for NET_NRF (and friends) and VETH so we can create a vrf

ipvlan: properly annotate rx_handler access
The rx_handler field is rcu-protected, but I forgot to use the
proper accessor while refactoring netif_is_ipvlan_port(). Such
function only check the rx_handler value, so it is safe, but we need
to properly read rx_handler via rcu_access_pointer() to avoid sparse
