Currently, all the device specific speed setting functions convert
SPEED_MAX to the actual speed of the port. This is used to default
CPU and DSA interfaces which do not have a fixed-link specification
in DT, which doesn't work correctly with the phylink integration.
In order to resolve this, we need access to this value, so make this
a separate function, and update mv88e6xxx_port_setup_mac() to use it.

The implementation appears not to support pause modes on anything
but RGMII, RGMII_TXID, MII and REVMII interface modes. Let phylink
know that detail.
(This may not be correct; particularly see the FIXMEs in this patch.)

DSA assumes that a bridge which has vlan filtering disabled is not
vlan aware, and ignores all vlan configuration. However, the kernel
software bridge code allows configuration in this state.
This causes the kernel's idea of the bridge vlan state and the
hardware state to disagree, so "bridge vlan show" indicates a correct
configuration but the hardware lacks all configuration. Even worse,
enabling vlan filtering on a DSA bridge immediately blocks all traffic
which, given the output of "bridge vlan show", is very confusing.
Provide an option that drivers can set to indicate they want to receive
vlan configuration even when vlan filtering is disabled. This is safe
for Marvell DSA bridges, which do not look up ingress traffic in the
VTU if the port is in 8021Q disabled state. Whether this change is
suitable for all DSA bridges is not known.

phy_error() is called from phy_interrupt() or phy_state_machine(), and
uses WARN_ON() to print a backtrace. The backtrace is not useful when
reporting a PHY error.
However, a system may contain multiple ethernet PHYs, and phy_error()
gives no clue which one caused the problem.
Replace WARN_ON() with a call to phydev_err() so that we can see which
PHY had an error, and also inform the user that we are halting the PHY.

Add support for configuring the LEDs. Macchiatobin has an oddity in
that the left LED goes out when the cable is connected, and flashes
when there's link activity. This is because the reset default for

ground. Add support for configuring the LED modes and polarities.

There are several places which open code comparing PHY IDs. Provide a
couple of helpers to assist with this, using a slightly simpler test
than the original:
- phy_id_compare() compares two arbitary PHY IDs and a mask of the
significant bits in the ID.
- phydev_id_compare() compares the bound phydev with the specified
PHY ID, using the bound driver's mask.

The at803x driver contains a function, at803x_match_phy_id(), which
tests whether the PHY ID matches the value passed, comparing phy_id
with phydev->phy_id and testing all bits that have a "one" in the
mask, phydev->drv->phy_id_mask.
This is the same test that is used to match the driver, with phy_id
replaced with the driver specified ID, phydev->drv->phy_id.
Hence, we already know the value of the bits being tested if we look
at phydev->drv->phy_id directly, and we do not require a complicated
test to check them. Test directly against phydev->drv->phy_id instead.

If we intend to use PCS operations, mac_pcs_get_state() will not be
implemented, so will be NULL. If we also intend to register the PCS
operations in mac_prepare() or mac_config(), then this leads to an
attempt to call NULL function pointer during phylink_start(). Avoid
this.

The SGMII PCS PHY needs to be updated with the link configuration in
the mac_link_up() call rather than in mac_config(). However,
mtk_sgmii_setup_mode_force() programs the SGMII block during
mac_config() when using 802.3z interface modes with the link
configuration.
Split that functionality from mtk_sgmii_setup_mode_force(), moving it
to a new mtk_sgmii_link_up() function, and call it from mac_link_up().
This does not look correct to me: 802.3z modes operate at a fixed
speed. The contents of mtk_sgmii_link_up() look more appropriate for
SGMII mode, but the original code definitely did not call
mtk_sgmii_setup_mode_force() for SGMII mode but only 802.3z mode.

Some firmware files trigger a PHY soft reset and don't wait for it to
be finished. PHY register writes directly after applying the firmware
may fail or provide unexpected results therefore. Fix this by waiting
for bit BMCR_RESET to be cleared after applying firmware.
There's nothing wrong with the referenced change, it's just that the
fix will apply cleanly only after this change.

When get_registers() fails in set_ethernet_addr(),the uninitialized
value of node_id gets copied over as the address.
So, check the return value of get_registers().
If get_registers() executed successfully (i.e., it returns
sizeof(node_id)), copy over the MAC address using ether_addr_copy()
(instead of using memcpy()).
Else, if get_registers() failed instead, a randomly generated MAC
address is set as the MAC address instead.

Tail dropping is enabled for a port when:
1. A source port consumes more packet buffers than the watermark encoded
in SYS:PORT:ATOP_CFG.ATOP.
AND
2. Total memory use exceeds the consumption watermark encoded in
SYS:PAUSE_CFG:ATOP_TOT_CFG.
The unit of these watermarks is a 60 byte memory cell. That unit is
programmed properly into ATOP_TOT_CFG, but not into ATOP. Actually when
written into ATOP, it would get truncated and wrap around.

clang static analysis reports this problem:

Attempt to free released memory
kfree(txq->buf);
^~~~~~~~~~~~~~~
When mvneta_txq_sw_init() fails to alloc txq->tso_hdrs,
it frees without poisoning txq->buf. The error is caught
in the mvneta_setup_txqs() caller which handles the error
by cleaning up all of the txqs with a call to
mvneta_txq_sw_deinit which also frees txq->buf.
Since mvneta_txq_sw_deinit is a general cleaner, all of the
partial cleaning in mvneta_txq_sw_deinit()'s error handling
is not needed.

The variable "i" isn't initialized back correctly after the first loop
under the label inst_rollback gets executed.
The value of "i" is assigned to be option_count - 1, and the ensuing
loop (under alloc_rollback) begins by initializing i--.
Thus, the value of i when the loop begins execution will now become
i = option_count - 2.
Thus, when kfree(dst_opts[i]) is called in the second loop in this
order, (i.e., inst_rollback followed by alloc_rollback),
dst_optsp[option_count - 2] is the first element freed, and
dst_opts[option_count - 1] does not get freed, and thus, a memory
leak is caused.
This memory leak can be fixed, by assigning i = option_count (instead of
option_count - 1).

Ethtool manual stated that the tx-timer is the "the amount of time the
device should stay in idle mode prior to asserting its Tx LPI". The
previous implementation for "ethtool --set-eee tx-timer" sets the LPI TW
timer duration which is not correct. Hence, this patch fixes the
"ethtool --set-eee tx-timer" to configure the EEE LPI timer.
The LPI TW Timer will be using the defined default value instead of
"ethtool --set-eee tx-timer" which follows the EEE LS timer implementation.
Changelog V2
*Not removing/modifying the eee_timer.
*EEE LPI timer can be configured through ethtool and also the eee_timer
module param.
*EEE TW Timer will be configured with default value only, not able to be
configured through ethtool or module param. This follows the implementation
of the EEE LS Timer.

Current neigh update event handler implementation takes reference to
neighbour structure, assigns it to nhe->n, tries to schedule workqueue task
and releases the reference if task was already enqueued. This results
potentially overwriting existing nhe->n pointer with another neighbour
instance, which causes double release of the instance (once in neigh update
handler that failed to enqueue to workqueue and another one in neigh update
workqueue task that processes updated nhe->n pointer instead of original
one):

neighbour pointer and removes the need for handling the case when task is
already enqueued.

When interface is attached while in promiscuous mode and with VLAN
filtering turned off, both configurations are not respected and VLAN
filtering is performed.
There are 2 flows which add the any-vid rules during interface attach:
VLAN creation table and set rx mode. Each is relaying on the other to
add any-vid rules, eventually non of them does.
Fix this by adding any-vid rules on VLAN creation regardless of
promiscuous mode.

Prior to this patch unloading an interface in promiscuous mode with RX
VLAN filtering feature turned off - resulted in a warning. This is due
to a wrong condition in the VLAN rules cleanup flow, which left the
any-vid rules in the VLAN steering table. These rules prevented
destroying the flow group and the flow table.
The any-vid rules are removed in 2 flows, but none of them remove it in
case both promiscuous is set and VLAN filtering is off. Fix the issue by
changing the condition of the VLAN table cleanup flow to clean also in
case of promiscuous mode.

Verify the configured FEC mode is supported by at least a single link
mode before applying the command. Otherwise fail the command and return
"Operation not supported".
Prior to this patch, the command was successful, yet it falsely set all
link modes to FEC auto mode - like configuring FEC mode to auto. Auto
mode is the default configuration if a link mode doesn't support the
configured FEC mode.

checksum and GSO. For other protocols, inform the stack to do the needed

The cited commit introduced the following coverity issue at function
mlx5_tc_ct_rule_to_tuple_nat:
- Memory - corruptions (OVERRUN)
Overrunning array "tuple->ip.src_v6.in6_u.u6_addr32" of 4 4-byte
elements at element index 7 (byte offset 31) using index
"ip6_offset" (which evaluates to 7).
In case of IPv6 destination address rewrite, ip6_offset values are
between 4 to 7, which will cause memory overrun of array
"tuple->ip.src_v6.in6_u.u6_addr32" to array
"tuple->ip.dst_v6.in6_u.u6_addr32".
Fixed by writing the value directly to array
"tuple->ip.dst_v6.in6_u.u6_addr32" in case ip6_offset values are
between 4 to 7.
