====================
FEC MDIO speedups
This patchset gives a number of speedups for MDIO with the FEC.
Replacing interrupt driven with polled IO brings a big speedup due to
the overheads of interrupts compared to the short time interval.
Clocking the bus faster, when the MDIO targets supports it, can double
the transfer rate. And suppressing the preamble, if devices support
it, makes each transaction faster.
By default the MDIO clock remains 2.5MHz and preables are used. But
these can now be controlled from the device tree. Since these are
generic properties applicable to more than just FEC, these have been
added to the generic MDIO binding documentation.

Measurements of the MDIO bus have shown that driving the MDIO bus

Replacing the completion interrupt with polled IO results in back to

interrupt handling has an overhead of 50us, and polled IO nearly

As explained in commit
fc25996e6f46 ("mlxsw: spectrum_router: Increase

the interface indexes of all the member nexthop devices.
To avoid many different nexthop groups ending up using the same key, the
above commit started hashing the interface indexes themselves before
they are XOR-ed.
However, in cases in which there are many nexthop groups that all use
the same nexthop device and only differ in the gateway IP, we can still
end up in a situation in which all the groups are using the same key.
This eventually leads to -EBUSY error from rhashtable during insertion.

net: dsa: sja1105: enable internal pull-down for RX_DV/CRS_DV/RX_CTL and RX_ER
Some boards do not have the RX_ER MII signal connected. Normally in such
situation, those pins would be grounded, but then again, some boards
left it electrically floating.
When sending traffic to those switch ports, one can see that the
N_SOFERR statistics counter is incrementing once per each packet. The
user manual states for this counter that it may count the number of
frames "that have the MII error input being asserted prior to or
up to the SOF delimiter byte". So the switch MAC is sampling an
electrically floating signal, and preventing proper traffic reception
because of that.
As a workaround, enable the internal weak pull-downs on the input pads
for the MII control signals. This way, a floating signal would be
internally tied to ground.
The logic levels of signals which _are_ externally driven should not be
bothered by this 40-50 KOhm internal resistor. So it is not an issue to
enable the internal pull-down unconditionally, irrespective of PHY
interface type (MII, RMII, RGMII, SGMII) and of board layout.

In case of success, igc_add_mac_filter() returns the index in

In fact, callers have extra code just to handle this returning

igc: Remove duplicate code in MAC filtering logic
This patch does a code refactoring in the MAC address filtering logic to
get rid of some duplicate code.
IGC driver has two functions to add MAC address filters that are pretty
much the same: igc_add_mac_filter() and igc_add_mac_filter_flags(). The
only difference is that the latter allows the callee to specify the
'flags' parameter while the former has it hard coded as zero. The same
rationale applies to filter deletion counterparts.
So this patch refactors igc_add_mac_filter() and igc_del_mac_filter() so
they handle the 'flags' parameters, removes the _flags() functions, and
fixes callees accordingly.

enetc: permit configuration of rx-vlan-filter with ethtool
Each ENETC station interface (SI) has a VLAN filter list and a port
flag (PSIPVMR) by which it can be put in "VLAN promiscuous" mode, which
enables the reception of VLAN-tagged traffic even if it is not in the
VLAN filtering list.
Currently the handling of this setting works like this: the port starts
off as VLAN promiscuous, then it switches to enabling VLAN filtering as
soon as the first VLAN is installed in its filter via
.ndo_vlan_rx_add_vid. In practice that does not work out very well,
because more often than not, the first VLAN to be installed is out of
the control of the user: the 8021q module, if loaded, adds its rule for
802.1p (VID 0) traffic upon bringing the interface up.
What the user is currently seeing in ethtool is this:
ethtool -k eno2
rx-vlan-filter: on [fixed]
which doesn't match the intention of the code, but the practical reality
of having the 8021q module install its VID which has the side-effect of
turning on VLAN filtering in this driver. All in all, a slightly
confusing experience.
So instead of letting this driver switch the VLAN filtering state by
itself, just wire it up with the rx-vlan-filter feature from ethtool,
and let it be user-configurable just through that knob, except for one
case, see below.
In promiscuous mode, it is more intuitive that all traffic is received,
including VLAN tagged traffic. It appears that it is necessary to set
the flag in PSIPVMR for that to be the case, so VLAN promiscuous mode is
also temporarily enabled. On exit from promiscuous mode, the setting
made by ethtool is restored.

net: mscc: ocelot: deal with problematic MAC_ETYPE VCAP IS2 rules
By default, the VCAP IS2 will produce a single match for each frame, on
the most specific classification.
Example: a ping packet (ICMP over IPv4 over Ethernet) sent from an IP
address of 10.0.0.1 and a MAC address of 96:18:82:00:04:01 will match
this rule:
tc filter add dev swp0 ingress protocol ipv4 \
flower skip_sw src_ip 10.0.0.1 action drop
but not this one:
tc filter add dev swp0 ingress \
flower skip_sw src_mac 96:18:82:00:04:01 action drop
Currently the driver does not really warn the user in any way about
this, and the behavior is rather strange anyway.
The current patch is a workaround to force matches on MAC_ETYPE keys
(DMAC and SMAC) for all packets irrespective of higher layer protocol.
The setting is made at the port level.
Of course this breaks all other non-src_mac and non-dst_mac matches, so
rule exclusivity checks have been added to the driver, in order to never
have rules of both types on any ingress port.
The bits that discard higher-level protocol information are set only
once a MAC_ETYPE rule is added to a filter block, and only for the ports
that are bound to that filter block. Then all further non-MAC_ETYPE
rules added to that filter block should be denied by the ports bound to
it.

Vinicius adds support for ETF offloading using the similar approach that
taprio offload used.
Kees Cook fixes a clang warning in the e1000e driver by moving the
declared variable either into the switch case that uses the variable or
lift them up into the main function body, to help the compiler.

igc: Fix default MAC address filter override
This patch fixes a bug when the user adds the first MAC address filter

When the first MAC address filter is added, it overwrites the default
MAC address filter configured at RAL[0] and RAH[0]. As consequence,
frames addressed to the interface MAC address are not sent to host
anymore.
This patch fixes the bug by calling igc_set_default_mac_filter() during
adapter init so the position 0 of adapter->mac_table[] is assigned to
the default MAC address.
