[ Upstream commit 926446ae24c03311a480fb96eb78f0ce7ea6d091 ]
AN restart triggered during KR training not only aborts the KR training
process but also move the HW to unstable state. Driver has to wait upto
500ms or until the KR training is completed before restarting AN cycle.

[ Upstream commit 579923d84b04abb6cd4cd1fd9974096a2dd1832b ]
There is difference in the TX Flow Control registers (TFCR) between the
revisions of the hardware. The older revisions of hardware used to have
single register per queue. Whereas, the newer revision of hardware (from
ver 30H onwards) have one register per priority.
Update the driver to use the TFCR based on the reported version of the
hardware.

[ Upstream commit f8ab263d4d48e6dab752029bf562f20a2ee630ed ]
There are cables that exist that can support speeds in excess of 10GbE.
The driver, however, restricts the EEPROM advertised nominal bitrate to
a specific range, which can prevent usage of cables that can support,
for example, up to 25GbE.
Rather than checking that an active or passive cable supports a specific
range, only check for a minimum supported speed.

[ Upstream commit 4998006c73afe44e2f639d55bd331c6c26eb039f ]
SFP+ active and passive cables are copper cables with fixed SFP+ end
connectors. Due to a misinterpretation of this, SFP+ active cables could
end up not being recognized, causing the driver to fail to establish a
connection.
Introduce a new enum in SFP+ cable types, XGBE_SFP_CABLE_FIBER, that is
the default cable type, and handle active and passive cables when they are
specifically detected.

[ Upstream commit 170a9e341a3b02c0b2ea0df16ef14a33a4f41de8 ]
The offset 12 (bit-rate) of EEPROM SFP DAC (passive) cables is expected
to be in the range 0x64 to 0x68. However, the 5 meter and 7 meter Molex
passive cables have the rate ceiling 0x78 at offset 12.
Add a quirk for Molex passive cables to extend the rate ceiling to 0x78.

[ Upstream commit 09c5f6bf11ac98874339e55f4f5f79a9dbc9b375 ]
The current XGBE code assumes that offset 6 of EEPROM SFP DAC (passive)
cables is NULL. However, some cables (the 5 meter and 7 meter Molex
passive cables) have non-zero data at offset 6. Fix the logic by moving
the passive cable check above the active checks, so as not to be
improperly identified as an active cable. This will fix the issue for
any passive cable that advertises 1000Base-CX in offset 6.

[ Upstream commit daf182d360e509a494db18666799f4e85d83dda0 ]
For each rate change command submission, the FW has to do a phy
power off sequence internally. For this to happen correctly, the
PLL re-initialization control setting has to be turned off before
sending mailbox commands and re-enabled once the command submission
is complete.

[ Upstream commit 84fe68eb67f9499309cffd97c1ba269de125ff14 ]
Normally, auto negotiation and reconnect should be automatically done by
the hardware. But there seems to be an issue where auto negotiation has
to be restarted manually. This happens because of link training and so
even though still connected to the partner the link never "comes back".
This needs an auto-negotiation restart.
Also, a change in xgbe-mdio is needed to get ethtool to recognize the
link down and get the link change message. This change is only
required in a backplane connection mode.

There are two reasons for this.
First, the xmit_more flag conceptually doesn't fit into the skb, as
xmit_more is not a property related to the skb.
Its only a hint to the driver that the stack is about to transmit another
packet immediately.
Second, it was only done this way to not have to pass another argument
to ndo_start_xmit().
We can place xmit_more in the softnet data, next to the device recursion.
The recursion counter is already written to on each transmit. The "more"
indicator is placed right next to it.
Drivers can use the netdev_xmit_more() helper instead of skb->xmit_more
to check the "more packets coming" hint.
skb->xmit_more is retained (but always 0) to not cause build breakage.
This change takes care of the simple s/skb->xmit_more/netdev_xmit_more()/
conversions. Remaining drivers are converted in the next patches.

The XGBE hardware has support for performing MDIO operations using an
MDIO command request. The driver mistakenly uses the mdio port address
as the MDIO command request device address instead of the MDIO command
request port address. Additionally, the driver does not properly check
for and create a clause 45 MDIO command.
Check the supplied MDIO register to determine if the request is a clause
45 operation (MII_ADDR_C45). For a clause 45 operation, extract the device
address and register number from the supplied MDIO register and use them
to set the MDIO command request device address and register number fields.
For a clause 22 operation, the MDIO request device address is set to zero
and the MDIO command request register number is set to the supplied MDIO
register. In either case, the supplied MDIO port address is used as the
MDIO command request port address.

The macro PHY_GBIT_FEAUTRES needs to change into a bitmap in order to
support link_modes. Remove its use from xgde by replacing it with its
definition.
Probably, the current behavior is wrong. It probably should be
ANDing not assigning.

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, so make sure the implementation in
this driver has returns 'netdev_tx_t' value, and change the function
return type to netdev_tx_t.

happening alongisde a move over to a bonafide statistics structure

After changing speed to 100Mbps as a result of auto-negotiation (AN),
some 10/100/1000Mbps SFPs indicate a successful link (no faults or loss
of signal), but cannot successfully transmit or receive data. These
SFPs required an extra auto-negotiation (AN) after the speed change in
order to operate properly. Add a quirk for these SFPs so that if the
outcome of the AN actually results in changing to a new speed, re-initiate
AN at that new speed.

Link training is always attempted when in KR mode, but the code is
structured to check if link training has been enabled before attempting
to perform it. Since that check will always be true, simplify the code
to always enable and start link training during KR auto-negotiation.

The driver currently sets an indication of whether the SFP supports, and
that the driver can obtain, diagnostics data. This isn't currently used
by the driver and the logic to set this indicator is flawed because the
field is cleared each time the SFP is checked and only set when a new SFP
is detected. Remove this field and the logic supporting it.

The comm_owned field can hide logic where double locking is attempted
