The initial marvell-88q2xxx driver only supported the Marvell 88Q2110
PHY without auto negotiation support. The reason documented states that
the provided initialization sequence did not to work. Now a method to
enable auto negotiation have been found by comparing the initialization
of other supported devices and an out-of-tree PHY driver.
Perform the minimal needed initialization of the PHY to get auto
negotiation working and remove the limitation that disables the auto
negotiation feature for the mv88q2110 device.
With this change a 1000Mbps full duplex link is able to be negotiated
between two mv88q2110 and the link works perfectly. The other side also
reflects the manually configure settings of the master device.

The soft reset implementations for mv88q2110 and mv88q2220 differ as the
later need to consider that auto negation is supported on mv88q2220
devices. In preparation of enabling auto negotiation on mv88q2110 merge
the two rest functions into a device generic one.
The mv88q2220 behavior is kept as is but extended to wait for the reset
bit to be clears before continuing, as was done previously on mv88q2220.

Despite supporting Auto MDI-X, it looks like Aquantia only supports
swapping pair (1,2) with pair (3,6) like it used to be for MDI-X on
100MBit/s networks.
When all 4 pairs are in use (for 1000MBit/s or faster) the link does not
come up with pair order is not configured correctly, either using
MDI_CFG pin or using the "PMA Receive Reserved Vendor Provisioning 1"
register.
Normally, the order of MDI pairs being either ABCD or DCBA is configured
by pulling the MDI_CFG pin.
However, some hardware designs require overriding the value configured
by that bootstrap pin. The PHY allows doing that by setting a bit in
"PMA Receive Reserved Vendor Provisioning 1" register which allows
ignoring the state of the MDI_CFG pin and another bit configuring
whether the order of MDI pairs should be normal (ABCD) or reverse
(DCBA). Pair polarity is not affected and remains identical in both
settings.
Introduce property "marvell,mdi-cfg-order" which allows forcing either
normal or reverse order of the MDI pairs from DT.
If the property isn't present, the behavior is unchanged and MDI pair
order configuration is untouched (ie. either the result of MDI_CFG pin
pull-up/pull-down, or pair order override already configured by the
bootloader before Linux is started).
Forcing normal pair order is required on the Adtran SDG-8733A Wi-Fi 7
residential gateway.

Add a cached FID bitmap. This mitigates the need to walk all VTU entries
to find the next free FID.
When flushing the VTU (during init), zero the FID bitmap. Use and
manipulate this bitmap from now on, instead of reading HW for the FID
map.
The repeated VTU walks are costly and can take ~40 mins if ~4000 vlans
are added. Caching the FID map reduces this time to <2 mins.

CLKGEN_LCPLL1_CORE_CLK).
- function calls that should only be done on Sparx5
(ethtool_op_get_ts_info())
- register writes that are chip-exclusive (MASK_CFG1/2, PGID_CFG1/2,
these are replicated for n_ports >32 on Sparx5).
The is_sparx5() function simply checks the target chip type, to
determine if this is a Sparx5 SKU or not.

The register macros are used to read and write to the switch registers.
The registers are largely the same on Sparx5 and lan969x, however in some
cases they differ. The differences can be one or more of the following:
target size, register address, register count, group address, group
count, group size, field position, field size.
In order to handle these differences, we introduce a new indirection
layer, that defines and maps them to corresponding values, based on the
platform. As the register macro arguments can now be non-constants, we
also add non-constant variants of FIELD_GET and FIELD_PREP.
Since the indirection layer contributes to longer macros, we have
changed the formatting of them slightly, to adhere to a 80 character
limit, and added a comment if a macro is platform-specific.
With these additions, we can reuse all the existing macros for
lan969x.

struct device *device_find_child(struct device *dev, const void *data,

The new API does not allow its match function (*match)() to modify
caller's match data @*data, but emac_sgmii_acpi_match(), as the old
API's match function, indeed modifies relevant match data, so it is
not suitable for the new API any more, solved by implementing the same

efx_rx_packet__check_len() when an RX packet (which was placed in a
single buffer by SG, i.e. n_frags == 1) has a length (from the RX
event) which is too long to fit in the RX buffer. If this occurs, we
drop the packet and fire a ratelimited netif_err().
The counter previously was not reported anywhere; add it to ethtool -S

Just RX and TX packet counts and TX bytes for now. We do not

stats.pkt_byte_sum selftest with "Drivers should always report

Per-queue counts are since the last time the queue was inited
(typically by efx_start_datapath(), on ifup or reconfiguration);
device-wide total (efx_get_base_stats()) is since driver probe.
This is not the same lifetime as rtnl_link_stats64, which uses
firmware stats which count since FW (re)booted; this can cause a
"Qstats are lower" or "RTNL stats are lower" failure in
stats.pkt_byte_sum selftest.
Move the increment of rx_queue->rx_packets to match the semantics
specified for netdev per-queue stats, i.e. just before handing
the packet to XDP (if present) or the netstack (through GRO).
