Change the driver's default behavior to prefer the largest available RX
buffer length supported by the device for DQO format, rather than always
using the hardcoded 2K default.
Previously, the driver would initialize with
`GVE_DEFAULT_RX_BUFFER_SIZE` (2K), even if the device advertised support
for a larger length (e.g., 4K).
Performance observations:
- With LRO disabled, we observed >10% improvement in RX single stream
throughput when MTU >=2048.
- With LRO enabled, we observed >10% improvement in RX single stream
throughput when MTU >=1460.
- No regressions were observed.

Add support for getting and setting the RX buffer length via the
ethtool ring parameters (`ethtool -g`/`-G`). The driver restricts the
allowed buffer length to 2048 (SZ_2K) by default and allows 4096 (SZ_4K)
based on device options.
As XDP is only supported when the `rx_buf_len` is 2048, the driver now
enforces this in two places:
1. In `gve_xdp_set`, rejecting XDP programs if the current buffer
length is not 2048.
2. In `gve_set_rx_buf_len_config`, rejecting buffer length changes if XDP
is loaded and the new length is not 2048.

Previously, enabling header split via `gve_set_hsplit_config` also
implicitly changed the RX buffer length to 4K (if supported by the
device). This coupled two settings that should be orthogonal; this patch
removes that side effect.
After this change, `gve_set_hsplit_config` only toggles the header
split configuration. The RX buffer length is no longer affected and
must be configured independently.

As per the previous commit, we have validated that the phy_intf_sel
value is one that is permissible for this SoC, so there is no need to
handle invalid PHY interface modes. We can also apply the other
configuration based upon the phy_intf_sel value rather than the
PHY interface mode.

x1000, x1600 and x1830 only accept RMII mode. PHY_INTF_SEL_RMII is only
selected with PHY_INTERFACE_MODE_RMII, and PHY_INTF_SEL_RMII has been
validated by the SoC's .valid_phy_intf_sel bitmask. Thus, checking the
interface mode in these functions becomes unnecessary. Remove these.
jz4775 is similar, except for a greater set of PHY_INTF_SEL_x valies.
Also remove the switch statement here.

In the current implementation, usbnet uses a fixed tx_qlen of:
USB2: 60 * 1518 bytes = 91.08 KB
USB3: 60 * 5 * 1518 bytes = 454.80 KB
Such large transmit queues can be problematic, especially for cellular
modems. For example, with a typical celluar link speed of 10 Mbit/s, a
fully occupied USB3 transmit queue results in:
454.80 KB / (10 Mbit/s / 8 bit/byte) = 363.84 ms
of additional latency.
This patch adds support for Byte Queue Limits (BQL) [1] to dynamically
manage the transmit queue size and reduce latency without sacrificing
throughput.
Testing was performed on various devices using the usbnet driver for
packet transmission:
- DELOCK 66045: USB3 to 2.5 GbE adapter (ax88179_178a)
- DELOCK 61969: USB2 to 1 GbE adapter (asix)
- Quectel RM520: 5G modem (qmi_wwan)
- USB2 Android tethering (cdc_ncm)
No performance degradation was observed for iperf3 TCP or UDP traffic,
while latency for a prioritized ping application was significantly
reduced. For example, using the USB3 to 2.5 GbE adapter, which was fully
utilized by iperf3 UDP traffic, the prioritized ping was improved from
1.6 ms to 0.6 ms. With the same setup but with a 100 Mbit/s Ethernet
connection, the prioritized ping was improved from 35 ms to 5 ms.

The ARL registers of BCM63XX embedded switches are somewhat unique. The
normal ARL table access registers have the same format as BCM5389, but
the ARL search registers differ:
* SRCH_CTL is at the same offset of BCM5389, but 16 bits wide. It does
not have more fields, just needs to be accessed by a 16 bit read.
* SRCH_RSLT_MACVID and SRCH_RSLT are aligned to 32 bit, and have shifted
offsets.
* SRCH_RSLT has a different format than the normal ARL data entry
register.
* There is only one set of ENTRY_N registers, implying a 1 bin layout.
So add appropriate ops for bcm63xx and let it use it.

When converting the Renesas network drivers to use flags from enum
hwtstamp_rx_filters to control when to timestamp packages instead of a
driver specific schema with bit-wise flags an error was made.
The bit-wise driver specific flags correct logic to set get_ts was:
q: RAVB_BE + tstamp_rx_ctrl: 0 => 0
q: RAVB_NC + tstamp_rx_ctrl: 0 => 0
q: RAVB_BE + tstamp_rx_ctrl: RAVB_RXTSTAMP_TYPE_V2_L2_EVENT => 0
q: RAVB_NC + tstamp_rx_ctrl: RAVB_RXTSTAMP_TYPE_V2_L2_EVENT => 1
q: RAVB_BE + tstamp_rx_ctrl: RAVB_RXTSTAMP_TYPE_ALL => 1
q: RAVB_NC + tstamp_rx_ctrl: RAVB_RXTSTAMP_TYPE_ALL => 1
The converted logic to use enum flags mapped tstamp_rx_ctrl as
0 to HWTSTAMP_FILTER_NONE
RAVB_RXTSTAMP_TYPE_V2_L2_EVENT to HWTSTAMP_FILTER_PTP_V2_L2_EVENT
RAVB_RXTSTAMP_TYPE_ALL to HWTSTAMP_FILTER_ALL
But the logic was incorrectly changed to:
q: RAVB_BE + tstamp_rx_ctrl: HWTSTAMP_FILTER_NONE => 1 (error)
q: RAVB_NC + tstamp_rx_ctrl: HWTSTAMP_FILTER_NONE => 0
q: RAVB_BE + tstamp_rx_ctrl: HWTSTAMP_FILTER_PTP_V2_L2_EVENT => 0
q: RAVB_NC + tstamp_rx_ctrl: HWTSTAMP_FILTER_PTP_V2_L2_EVENT => 1
q: RAVB_BE + tstamp_rx_ctrl: HWTSTAMP_FILTER_ALL => 1
q: RAVB_NC + tstamp_rx_ctrl: HWTSTAMP_FILTER_ALL => 0 (error)
This change restores the converted flag check to the correct logic of
the bit-wise driver specific flags.

Use the PHY_INTF_SEL_x values directly rather than the driver private
LPC18XX_CREG_CREG6_ETHMODE_x definitions, and convert
LPC18XX_CREG_CREG6_ETHMODE_MASK to use GENMASK().

The lan8814 is a quad-phy and it is using QSGMII towards the MAC.
The problem is that everytime when one of the ports is configured then
the PCS is reseted for all the PHYs. Meaning that the other ports can
loose traffic until the link is establish again.
To fix this, do the reset one time for the entire PHY package.

Two additional bytes in front of each frame received into the RX FIFO if
SHIFT16 is set, so we need to subtract the extra two bytes from pkt_len
to correct the statistic of rx_bytes.

Add all statistics described under the "Implementation Requirements"
section of the PSP Architecture Specification:
Rx successfully decrypted PSP packets:
psp_rx_pkts : Number of packets decrypted successfully
psp_rx_bytes : Number of bytes decrypted successfully
Rx PSP authentication failure statistics:
psp_rx_pkts_auth_fail : Number of PSP packets that failed authentication
psp_rx_bytes_auth_fail : Number of PSP bytes that failed authentication
Rx PSP bad frame error statistics:
psp_rx_pkts_frame_err;
psp_rx_bytes_frame_err;
Rx PSP drop statistics:
psp_rx_pkts_drop : Number of PSP packets dropped
psp_rx_bytes_drop : Number of PSP bytes dropped
Tx successfully encrypted PSP packets:
psp_tx_pkts : Number of packets encrypted successfully
psp_tx_bytes : Number of bytes encrypted successfully
Tx drops:
tx_drop : Number of misc psp related drops
The above can be seen using the ynl cli:

Enable Open Alliance TC14 (OATC14) 10Base-T1S cable diagnostic feature
for Microchip LAN867x Rev.D0 PHY by implementing `cable_test_start` and
`cable_test_get_status` using the generic C45 functions. This allows the
`ethtool` utility to perform cable diagnostic tests directly on the PHY,
improving network troubleshooting and maintenance.

Add support for Open Alliance TC14 (OATC14) 10BASE-T1S PHYs cable
diagnostic feature.
This patch implements:
- genphy_c45_oatc14_cable_test_start() to initiate a cable test
- genphy_c45_oatc14_cable_test_get_status() to retrieve test results
- Helper function to map PHY cable test status to ethtool result codes
- Function declarations and exports for use by PHY drivers
This enables ethtool to report ok, open, short, and undetectable cable
conditions on OATC14 10Base-T1S PHYs.

Once the netshaper is created for MANA, the current bandwidth
is reported in debugfs like this:
$ sudo ./tools/net/ynl/pyynl/cli.py \
--spec Documentation/netlink/specs/net_shaper.yaml \
--do set \
--json '{"ifindex":'3',
"handle":{ "scope": "netdev", "id":'1' },
"bw-max": 200000000 }'
None
$ sudo cat /sys/kernel/debug/mana/1/vport0/current_speed
200
After the shaper is deleted, it is expected to report
the maximum speed supported by the SKU. But currently it is
reporting 0, which is incorrect.
Fix this inconsistency, by resetting apc->speed to apc->max_speed
during deletion of the shaper object. This will improve
readability and debuggability.

EN7581 and AN7583 SoCs are capable of DMA mapping non-linear tx skbs on
non-consecutive DMA descriptors. This feature is useful when multiple
flows are queued on the same hw tx queue since it allows to fully utilize
the available tx DMA descriptors and to avoid the starvation of
high-priority flow we have in the current codebase due to head-of-line
blocking introduced by low-priority flows.

Instead of translating to/from driver specific flags for packet time
stamp control use the common flags directly. This simplifies the driver
as the translating code can be removed while at the same time making it
clear the flags are not flags written to hardware registers.
The change from a device specific bit-field track variable to the common
enum datatypes forces us to touch the ravb_rx_rcar_hwstamp() in a non
trivial way. To make this cleaner and easier to understand expand the
nested conditions.
