The change to polled IO for MDIO completion assumes that MII events
are only generated for MDIO transactions. However on some SoCs writing
to the MII_SPEED register can also trigger an MII event. As a result,
the next MDIO read has a pending MII event, and immediately reads the
data registers before it contains useful data. When the read does
complete, another MII event is posted, which results in the next read
also going wrong, and the cycle continues.
By writing 0 to the MII_DATA register before writing to the speed
register, this MII event for the MII_SPEED is suppressed, and polled
IO works as expected.

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

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
accessed as RCU pointer, containing all sample values including

values and the race condition described above.

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
