Now that all tests have a fixture object move from a global
list of tests to a list of tests per fixture.
Order of tests may change as we will now group and run test
fixture by fixture, rather than in declaration order.

New sysctl to turn off nexthop API compat mode
Currently route nexthop API maintains user space compatibility
with old route API by default. Dumps and netlink notifications
support both new and old API format. In systems which have
moved to the new API, this compatibility mode cancels some
of the performance benefits provided by the new nexthop API.
This patch adds new sysctl nexthop_compat_mode which is on
by default but provides the ability to turn off compatibility
mode allowing systems to run entirely with the new routing
API if they wish to. Old route API behaviour and support is
not modified by this sysctl
v4:
- Use davids note for Documenting the sysctl
- test with latest iproute2 and adjust 'pref'
v3:
- Document new sysctl
- move sysctl to use proc_dointvec_minmax with 0 and 1 values
- selftest: remove pref medium in ipv6 test
v2:
- Incorporate David Aherns pointers on covering dumps and
nexthop deletes. Also use one ipv4 sysctl to cover
both ipv4 and ipv6 (I see it is done that way for many
others)
- Added a selftest to cover dump and notfications for nexthop
api compat mode

mlxsw: Rework matchall offloading plumbing
Jiri says:
Currently the matchall and flower are handled by registering separate
callbacks in mlxsw. That leads to faulty indication "in_hw_count 2" in
filter show command for every inserted flower filter. That happens
because matchall callback just blindly returns 0 for it and it is
wrongly accounted for as "the offloader".
I inspected different ways to fix this problem. The only clean solution
is to rework handling of matchall in mlxsw a bit. The driver newely
registers one callback for bound block which is called for both matchall
and flower filter insertions.
On the way, iron out the matchall code a bit, push it into a separate
file etc.

Currently, only the psample_group is accessed using RCU on RX path.
However, it is possible (unlikely) that other sample values get change
during RX processing. Fix this by having the port->sample struct

Two bits in RxConfig are controlled by the following dev->feature's:

We have to take care that RxConfig gets fully configured in
rtl_hw_start() after e.g. resume from hibernation. Therefore:
- Factor out setting the feature-controlled RxConfig bits to a new
function rtl_set_rx_config_features() that is called from
rtl8169_set_features() and rtl_hw_start().
- Don't deal with RX_VLAN_8125 in rtl_init_rxcfg(), it will be set
by rtl_set_rx_config_features().
- Don't handle NETIF_F_RXALL in rtl_set_rx_mode().

net: bridge: mrp: Add support for Media Redundancy Protocol(MRP)
Media Redundancy Protocol is a data network protocol standardized by
International Electrotechnical Commission as IEC 62439-2. It allows rings of
Ethernet switches to overcome any single failure with recovery time faster than
STP. It is primarily used in Industrial Ethernet applications.
Based on the previous RFC[1][2][3][4][5], and patches[6][7][8], the MRP state
machine and all the timers were moved to userspace, except for the timers used
to generate MRP Test frames. In this way the userspace doesn't know and should
not know if the HW or the kernel will generate the MRP Test frames. The
following changes were added to the bridge to support the MRP:
- the existing netlink interface was extended with MRP support,
- allow to detect when a MRP frame was received on a MRP ring port
- allow MRP instance to forward/terminate MRP frames
- generate MRP Test frames in case the HW doesn't have support for this
To be able to offload MRP support to HW, the switchdev API was extend.
With these changes the userspace doesn't do the following because already the
kernel/HW will do:
- doesn't need to forward/terminate MRP frames
- doesn't need to generate MRP Test frames
- doesn't need to detect when the ring is open/closed.
The userspace application that is using the new netlink can be found here[9].
The current implementation both in kernel and userspace supports only 2 roles:
MRM - this one is responsible to send MRP_Test and MRP_Topo frames on both
ring ports. It needs to process MRP_Test to know if the ring is open or
closed. This operation is desired to be offloaded to the HW because it
requires to generate and process up to 4000 frames per second. Whenever it
detects that the ring is open it sends MRP_Topo frames to notify all MRC about
changes in the topology. MRM needs also to process MRP_LinkChange frames,
these frames are generated by the MRC. When the ring is open then the state
of both ports is to forward frames and when the ring is closed then the
secondary port is blocked.
MRC - this one is responsible to forward MRP frames between the ring ports.
In case one of the ring ports gets a link down or up, then MRC will generate
a MRP_LinkChange frames. This node should also process MRP_Topo frames and to
clear its FDB when it receives this frame.
Userspace
Deamon +----------+ Client
+
|
+--------------|-----------------------------------------+
Kernel |
+ Netlink
| + Interrupt
| |
+--------------|------------------------------|----------+
HW | Switchdev |
+ |
The user interacts using the client (called 'mrp'), the client talks to the
deamon (called 'mrp_server'), which talks with the kernel using netlink. The
kernel will try to offload the requests to the HW via switchdev API.
If this will be accepted then in the future the netlink interface can be
expended with multiple attributes which are required by different roles of the
MRP. Like Media Redundancy Automanager(MRA), Media Interconnect Manager(MIM) and
Media Interconnect Client(MIC).

To integrate MRP into the bridge, the bridge needs to do the following:
- detect if the MRP frame was received on MRP ring port in that case it would be
processed otherwise just forward it as usual.
- enable parsing of MRP
- before whenever the bridge was set up, it would set all the ports in
forwarding state. Add an extra check to not set ports in forwarding state if
the port is an MRP ring port. The reason of this change is that if the MRP
instance initially sets the port in blocked state by setting the bridge up it
would overwrite this setting.

Implement the MRP API.
In case the HW can't generate MRP Test frames then the SW will try to generate
the frames. In case that also the SW will fail in generating the frames then a
error is return to the userspace. The userspace is responsible to generate all
the other MRP frames regardless if the test frames are generated by HW or SW.
The forwarding/termination of MRP frames is happening in the kernel and is done
by the MRP instance. The userspace application doesn't do the forwarding.
