of it was debug functionality.
- most of deficetree bindings was removed. Not every thing made sense

qed*: Improve performance on 100G link for offload protocols
This patch series modifies the current implementation of PF selection.
The refactoring of the llh code enables setting additional filters
(mac / protocol) per PF, and improves performance for offload protocols
(RoCE, iWARP, iSCSI, fcoe) on 100G link (was capped at 90G per single
PF).
Improved performance on 100G link is achieved by configuring engine
affinty to each PF.
The engine affinity is read from the Management FW and hw is configured accordingly.
A new hw resource called PPFID is exposed and an API is introduced to utilize
it. This additional resource enables setting the affinity of a PF and providing
more classification rules per PF.
qedr,qedi,qedf are also modified as part of the series. Without the
changes functionality is broken.
v1 --> v2
---------
- Remove iWARP module parameter. Instead use devlink param infrastructure
for setting the iwarp_cmt mode. Additional patch added to the series for

net: mvpp2: Classifier updates, RSS
Here is a set of updates for the PPv2 classifier, the main feature being
the support for steering to RSS contexts, to leverage all the available
RSS tables in the controller.
The first two patches are non-critical fixes for the classifier, the
first one prevents us from allocating too much room to store the
classification rules, the second one configuring the C2 engine as
suggested by the PPv2 functionnal specs.
Patches 3 to 5 introduce support for RSS contexts in mvpp2, allowing us
to steer traffic to dedicated RSS tables.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
When steering to an RXQ, we can perform an extra RSS step to assign a
queue from an RSS table.
This is done by setting the RSS_EN attribute in the C2 engine. In that
case, the RXQ that is assigned is the global RSS context id, that is
then translated to an RSS table using the RXQ2RSS table.
An example using ethtool to steer to RXQ 2 and 3 would be :
ethtool -X eth0 weight 0 0 1 1 context new
(This would print the allocated context id, let's say it's 1)
ethtool -N eth0 flow-type udp4 dst-port 1234 context 1 loc 0
The hash parameters are the ones that are globally configured for RSS :
ethtool -N eth0 rx-flow-hash udp4 sdfn
When an RSS context is removed while there are active classification
rules using this context, these rules are removed.

The PPv2 controller has 8 RSS tables that are shared across all ports on
a given PPv2 instance. The previous implementation allocated one table
per port, leaving others unused.
By using RSS contexts, we can make use of multiple RSS tables per
port, one being the default table (always id 0), the other ones being
used as destinations for flow steering, in the same way as rx rings.
This commit introduces RSS contexts management in the PPv2 driver. We
always reserve one table per port, allocated when the port is probed.
The global table list is stored in the struct mvpp2, as it's a global
resource. Each port then maintains a list of indices in that global
table, that way each port can have it's own numbering scheme starting
from 0.
One limitation that seems unavoidable is that the hashing parameters are
shared across all RSS contexts for a given port. Hashing parameters for
ctx 0 will be applied to all contexts.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
struct boo entry[];
};
instance = kzalloc(sizeof(struct foo) + count * sizeof(struct boo), GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);
This code was detected with the help of Coccinelle.

[ Thanks to the introducion of selftests this series ended up being a misc
of improvements and the selftests additions per-se. ]
This introduces selftests support in stmmac driver. We add 9 basic sanity

more tests can easily be added in the future and can be run in virtually
any MAC/GMAC/QoS/XGMAC platform.
Having this we can find regressions and missing features in the driver
while at the same time we can check if the IP is correctly working.
We have been using this for some time now and I do have more tests to
submit in the feature. My experience is that although writing the tests
adds more development time, the gain results are obvious.
I let this feature optional within the driver under a Kconfig option.
