When mvpp2 configures the flow control modes in mvpp2_xlg_config() for
10G mode, it only ever set the flow control enable bits.  There is no
mechanism to clear these bits, which means that userspace is unable to
use standard APIs to disable flow control (the only way is to poke the
register directly.)

Fix the missing bit clearance to allow flow control to be disabled.
This means that, by default, as there is no negotiation in 10G modes
with mvpp2, flow control is now disabled rather than being rx-only.

Add support for runtime determination of what the PHY supports, by
adding a new function to the phy driver. The get_features call should
set the phydev->supported member with the features the PHY supports.
It is only called if phydrv->features is NULL.

This requires minor changes to pause. The PHY driver should not set
pause abilities, except for when it has odd cause capabilities, e.g.
pause cannot be disabled. With this change, phydev->supported already
contains the drivers abilities, including pause. So rather than
considering phydrv->features, look at the phydev->supported, and
enable pause if neither of the pause bits are already set.

Function tls_sw_recvmsg() dequeues multiple records from stream parser
and decrypts them. In case the decryption is done by async accelerator,
the records may get submitted for decryption while the previous ones may
not have been decryted yet. For tls1.3, the record type is known only
after decryption. Therefore, for tls1.3, tls_sw_recvmsg() may submit
records for decryption even if it gets 'handshake' records after 'data'
records. These intermediate 'handshake' records may do a key updation.
By the time new keys are given to ktls by userspace, it is possible that
ktls has already submitted some records i(which are encrypted with new
keys) for decryption using old keys. This would lead to decrypt failure.
Therefore, async decryption of records should be disabled for tls1.3.

====================
mvpp2 phylink fixes

Having spent a while debugging issues with Sven Auhagen, it appears
that the mvpp2 network driver's phylink support isn't quite correct.

This series fixes that up, but, despite being tested locally, by
Sven, and by Antoine, I would prefer it to be applied to net-next
so that there is time for more people to test before it hits -rc or
stable backports.

The symptoms were that although PHYs would come up, the GMAC never
reported that the link was up, or in some cases it did report link
up but packets would not flow.  Various approaches were tried to
work around that, such as switching to in-band negotiation from
PHY mode, but ultimately the problem was in the way mvpp2 was being
programmed.

This series addresses that by, essentially, making mvpp2 follow the
same implementation pattern as mvneta: we configure the GMAC in three
stages:

1) the PHY interface mode
2) the negotiation advert
3) the negotiation style

Another issue is that mvpp2 was always taking the link down each time
its mac_config method was called: this is disruptive when the link is
already up, and we're just updating settings such as flow control.
There are some circumstances where we make the call despite there
being no changes (eg, when phylink is polling a GPIO or using a custom
link state function.)

This series depends on two previous patches already sent for net-next:
  net: marvell: mvpp2: fix lack of link interrupts
  net: marvell: mvpp2: use phy_interface_mode_is_8023z() helper

There is one last patch which deals with link status interrupts, which
I'll send separately because I think there's other considerations, but
that should not hold up this series of patches.
