This is port of a fix from i40e commit 2ad1274fa3 ("i40e: don't
report link up for a VF who hasn't enabled queues")
Older VF drivers do not respond well to receiving a link
up notification before queues are enabled. This can cause their state
machine to think that it is safe to send traffic. This results in a Tx
hang on the VF.
Record whether the PF has actually enabled queues for the VF. When
reporting link status, always report link down if the queues aren't
enabled. In this way, the VF driver will never receive a link up
notification until after its queues are enabled.

When a PFR (or bigger reset) occurs, the device clears the VF_MBX_ARQLEN
register for all VFs. But if a VFR is triggered by a VF, the device does
NOT clear this register, and the VF driver will never see the reset.
When this happens, the VF driver will eventually timeout and attempt
recovery, and usually it will be successful. But this makes resets take
a long time and there are occasional failures.
We cannot just blithely clear this register on every reset; this has
been shown to cause synchronization problems when a PFR is triggered
with a large number of VFs.
Fix this by clearing VF_MBX_ARQLEN when the reset source is not PFR.
GlobR will trigger PFR, so this test catches that occurrence as well.

====================
This is a four patch series of various barrier, {READ, WRITE}_ONCE
cleanups in the AF_XDP socket code. More details can be found in the
corresponding commit message. Previous revisions: v1 [4] and v2 [5].
For an AF_XDP socket, most control plane operations are done under the
control mutex (struct xdp_sock, mutex), but there are some places
where members of the struct is read outside the control mutex. The
dev, queue_id members are set in bind() and cleared at cleanup. The
umem, fq, cq, tx, rx, and state member are all assigned in various
places, e.g. bind() and setsockopt(). When the members are assigned,
they are protected by the control mutex, but since they are read
outside the mutex, a WRITE_ONCE is required to avoid store-tearing on
the read-side.
Prior the state variable was introduced by Ilya, the dev member was
used to determine whether the socket was bound or not. However, when
dev was read, proper SMP barriers and READ_ONCE were missing. In order
to address the missing barriers and READ_ONCE, we start using the
state variable as a point of synchronization. The state member
read/write is paired with proper SMP barriers, and from this follows
that the members described above does not need READ_ONCE statements if
used in conjunction with state check.
To summarize: The members struct xdp_sock members dev, queue_id, umem,
fq, cq, tx, rx, and state were read lock-less, with incorrect barriers
and missing {READ, WRITE}_ONCE. After this series umem, fq, cq, tx,
rx, and state are read lock-less. When these members are updated,
WRITE_ONCE is used. When read, READ_ONCE are only used when read
outside the control mutex (e.g. mmap) or, not synchronized with the
state member (XSK_BOUND plus smp_rmb())

read/write is paired with proper SMP barriers, and from this follows
that the members described above does not need READ_ONCE if used in
conjunction with state check.
In all syscalls and the xsk_rcv path we check if state is
XSK_BOUND. If that is the case we do a SMP read barrier, and this
implies that the dev, umem and all rings are correctly setup. Note
that no READ_ONCE are needed for these variable if used when state is
XSK_BOUND (plus the read barrier).
To summarize: The members struct xdp_sock members dev, queue_id, umem,
fq, cq, tx, rx, and state were read lock-less, with incorrect barriers
and missing {READ, WRITE}_ONCE. Now, umem, fq, cq, tx, rx, and state

(XSK_BOUND plus smp_rmb())
Note that dev and queue_id do not need a WRITE_ONCE or READ_ONCE, due
to the introduce state synchronization (XSK_BOUND plus smp_rmb()).
Introducing the state check also fixes a race, found by syzcaller, in
xsk_poll() where umem could be accessed when stale.

gianfar: some assorted cleanup
This is a cleanup series for the gianfar Ethernet driver, following up a
discussion in [1]. It is intended to precede a conversion of gianfar from
PHYLIB to PHYLINK API, which will be submitted later in its version 2.
However, it won't make a conversion cleaner, except for the last patch in
this series. Obviously this series is not intended for -stable.
The first patch looks super controversial to me, as it moves lots of code
around for the sole purpose of getting rid of static forward declarations
in two translation units. On the other hand, this change is purely
mechanical and cannot do any harm other than cluttering git blame output.
I can prepare an alternative patch for only swapping adjacent functions
around, if necessary.
The second patch is a trivial follow-up to the first one, making functions
that are only called from the same translation unit static.
The third patch removes some now unused macro and structure definitions
from gianfar.h, slipped away from various cleanups in the past.
The fourth patch, also suggested in [1], makes the driver consistently use
PHY connection type value obtained from a Device Tree node, instead of
ignoring it and using the one auto-detected by MAC, when connecting to PHY.
Obviously a value has to be specified correctly in DT source, or omitted
altogether, in which case the driver will fall back to auto-detection. When
querying a DT node, the driver will also take both applicable properties
into account by making a proper API call instead of open-coding the lookup
half-way correctly.

Historically, gianfar only used phy-connection-type DT property when
connected to PHY in the rgmii-id mode. It ignored the property otherwise,
relying on the connection type auto-detection carried out by MAC and
providing that reconstructed mode to of_phy_connect(). It also did not
consider alternative phy-mode property at all.
Make the driver properly query DT node for PHY connection type first and
use an obtained value if it was specified there. Otherwise, if a particular
DT relies on connection type auto-detection, fall back to reconstructing
the value from MAC registers, as before.
