Implement read and write access to IEEE 802.3 Clause 45 Ethernet
phy registers while making use of new mdiobus_c45_regad and
mdiobus_c45_devad helpers.

Instead of returning -1 (-EPERM) when MDIO bus is stuck busy
while writing or 0xffff if it happens while reading, return the
appropriate -ETIMEDOUT. Also fix return type to int instead of u32.
Refactor functions to use bitfield helpers instead of having various
masking and shifting constants in the code, which also results in the
register definitions in the header file being more obviously related
to what is stated in the MediaTek's Reference Manual.

This patch adds support for scatter gather DMA. DMA in PMAC splits
the packet into several buffers when the MTU on the CPU port is
less than the MTU of the switch. The first buffer starts at an
offset of NET_IP_ALIGN. In subsequent buffers, dma ignores the
offset. Thanks to this patch, the user can still connect to the
device in such a situation. For normal configurations, the patch
has no effect on performance.

Moreover, as stated in [1], dma_set_mask() with a 64-bit mask will never
fail if dev->dma_mask is non-NULL.
So, if it fails, the 32 bits case will also fail for the same reason.

hardware information needed by hclge(vf)_cmd_send. There are a little

Set SMFS (SW-managed flow steering) as a default steering mode
instead of DMFS (device-managed flow steering)
In SMFS, the driver writes the STEs (Steering Table Entries) directly
to the device's ICM, which allows for a higher rule insertion rate
than through using FW command interface, as it is done in DMFS.
SMFS/DMFS steering modes can be configured through devlink param
'flow_steering_mode'. The possible values are 'smfs' or 'dmfs'.
The desired 'flow_steering_mode' param value should be set before
enabling switchdev mode.
Example:
# devlink dev param set pci/0000:05:00.0 name flow_steering_mode smfs
# devlink dev eswitch set pci/0000:05:00.0 mode switchdev

Every matcher has RX and TX paths. When a new matcher is created, its RX
and TX start/end anchors are connected to the respective RX and TX anchors
of the previous and next matchers.
This creates a potential performance issue: when a certain rule is added
to a matcher, in many cases it is RX or TX only rule, which may create a
long chain of RX/TX-only paths w/o the actual rules.
This patch aims to handle this issue.
RX and TX matchers are now handled separately: matcher connection in the
matchers chain is split into two separate lists: RX only and TX only.
when a new matcher is created, it is initially created 'detached' - its
RX/TX members are not inserted into the table's matcher list.
When an actual rule is added, only its appropriate RX or TX nic matchers
are then added to the table's nic matchers list and inserted into its
place in the chain of matchers.
I.e., if the rule that is being added is an RX-only rule, only the RX
part of the matcher will be connected to the chain, while TX part of the
matcher remains detached and doesn't prolong the TX chain of the matchers.
Same goes for rule deletion: when the last RX/TX rule of the nic matcher
is destroyed, the nic matcher is removed from its list.
