Currently the FPGA IPsec is the only hw implementation of the IPsec
acceleration api, and so the mlx5_accel_esp_create_hw_context was
wrongly made to suit this HW api, among other in its parameter list
and some of its parameter endianness.
This implementation might not be suitable for different HW.
Refactor by group and pass all function arguments of
mlx5_accel_esp_create_hw_context in common mlx5_accel_esp_xfrm_attrs
struct field of mlx5_accel_esp_xfrm struct and correct the endianness
according to the HW being called.

The cited commit relies on include <net/geneve.h> being included
implicitly prior to include "en_accel/en_accel.h".
This mandates that all files that needs to include en_accel.h
to redantantly include net/geneve.h.
Include net/geneve.h explicitly at "en_accel/en_accel.h" to avoid
undesired constrain as above.

Currently the IPsec acceleration capability function is also used
at IPsec fpga capable device code.
This could cause a future bug as the acceleration layer is agnostic
to the device implementing its API.
Fix by using the IPsec FPGA capability function instead of acceleration
layer capability function in case of FPGA IPsec only related operations.
Downstream patches will add support for Connect-X IPsec, this can avoid
a future bug.

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.

An MDIO transaction normally starts with 32 1s as a preamble. However
not all devices requires such a preamble. Add a device tree property
which allows the preamble to be suppressed. This will half the size of
the MDIO transaction, allowing faster transactions. But it should only
be used when all devices on the bus support suppressed preamble.

MDIO busses typically operate at 2.5MHz. However many devices can
operate at faster speeds. This then allows more MDIO transactions per
second, useful for Ethernet switch statistics, or Ethernet PHY TDR
data. Allow the bus speed to be configured, using the standard
"clock-frequency" property, which i2c busses use to indicate the bus
speed. Before using this property, ensure all devices on the bus do
actually support the requested clock speed.

Measurements of the MDIO bus have shown that driving the MDIO bus
using interrupts is slow. Back to back MDIO transactions take about
90us, with 25us spent performing the transaction, and the remainder of
the time the bus is idle.
Replacing the completion interrupt with polled IO results in back to
back transactions of 40us. The polling loop waiting for the hardware
to complete the transaction takes around 28us. Which suggests
interrupt handling has an overhead of 50us, and polled IO nearly
halves this overhead, and doubles the MDIO performance.

Cleaned up the return values for igc_add_mac_filter(), where the return

or failure. Fix the return value of igc_uc_unsync() as well. Refactor
the igc driver in several functions to help reduce the convoluted logic
and simplify the driver filtering mechanisms. Improve the MAC address
checks when adding a MAC filter. Lastly, improve the log messages
related to MAC address filtering to ease debugging.

As explained in commit fc25996e6f46 ("mlxsw: spectrum_router: Increase
scale of IPv6 nexthop groups"), each nexthop group is hashed by XOR-ing
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.
Improve the situation by also making the gateway IP part of the key.

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.

With this patch we might traverse mac_table twice in some situations,

The IGC_MAC_STATE_QUEUE_STEERING bit in mac_table[i].state is
utilized to indicate that frames matching the filter are assigned to
mac_table[i].queue. This bit is not strictly necessary since we can
convey the same information as follows: queue == -1 means queue
assignment is disabled, otherwise it is enabled.
In addition to make the code simpler, this change fixes some awkward
situations where we pass a complete misleading 'queue' value such as in
igc_uc_sync().
So this patch removes IGC_MAC_STATE_QUEUE_STEERING and also takes the

Current igc_rar_set_index() implementation is a bit convoluted so this
patch does some code refactoring to improve it.
The helper igc_rar_set_index() is about writing MAC filter settings into
hardware registers. Logic such as address validation belongs to
functions upper in the call chain such as igc_set_mac() and
igc_add_mac_filter(). So this patch moves the is_valid_ether_addr() call
to igc_add_mac_filter(). No need to touch igc_set_mac() since it already
checks it.
The variables 'rar_low' and 'rar_high' represent the value in registers
RAL and RAH so we rename them to 'ral' and 'rah', respectively, to
match the registers names.
To make it explicit, filter settings are passed as arguments to the
function instead of reading them from adapter->mac_table "under the
hood". Also, the function was renamed to igc_set_mac_filter_hw to make
it more clear what it does.
Finally, the patch removes some wrfl() calls and comments not needed.
