AC5X spec says PHY init complete bit must be polled until zero.
We see cases in which timeout can take longer than the standard
calculation on AC5X, which is expected following the spec comment above.
According to the spec, we must wait as long as it takes for that bit to
toggle on AC5X.
Cap that with 100 delay loops so we won't get stuck forever.

The introduction of sg_miter was a bit sloppy as it didn't
exactly mimic the semantics of the old code on multiblock reads
and writes: these like you to:
- Advance to the first sglist entry *before* starting to read
any blocks from the card.
- Advance and check availability of the next entry *right after*
processing one block.
Not checking if we have more sglist entries right after
reading a block will lead to this not being checked until we
return to the callback to read out more blocks, i.e. until the
next interrupt arrives. Since the last block is the last one
(no more data will arrive) there will not be a next interrupt,
and we will be waiting forever resulting in a timeout for
command 18 when reading multiple blocks.
The same bug was fixed also in the writing of multiple blocks.

The sg_miter used to loop over the returned sglist from a
transfer in the esdhc subdriver for SDHCI can be called
from atomic context so the miter needs to be atomic.
sdhci_request_done() is always called from process context,
either as a work or as part of the threaded interrupt handler,
but the one case when we are actually calling .request_done()
from an atomic context is in sdhci_irq().
Fix this by flagging the miter atomic so we always use
kmap_atomic().

Andrew Lunn says:
====================
drivers: net: Convert EEE handling to use linkmode bitmaps
EEE has until recently been limited to lower speeds due to the use of
the legacy u32 for link speeds. This restriction has been lifted, with
the use of linkmode bitmaps, added in the following patches:
1f069de636 ethtool: add linkmode bitmap support to struct ethtool_keee
1d756ff13d ethtool: add suffix _u32 to legacy bitmap members of struct ethtool_keee
285cc15cc5 ethtool: adjust struct ethtool_keee to kernel needs
0b3100bc8f ethtool: switch back from ethtool_keee to ethtool_eee for ioctl
d80a523353 ethtool: replace struct ethtool_eee with a new struct ethtool_keee on kernel side
This patchset converts the remaining MAC drivers still using the old
_u32 to link modes.
A couple of Intel drivers do odd things with EEE, setting the autoneg
bit. It is unclear why, no other driver does, ethtool does not display
it, and EEE is always negotiated. One patch in this series deletes
this code.
With all users of the legacy _u32 changed to link modes, the _u32
values are removed from keee, and support for them in the ethtool core
is removed.

There's a somewhat common pattern of using FIELD_PREP()
even for single bits, e.g.
cmd->info1 |= FIELD_PREP(HTT_SRNG_SETUP_CMD_INFO1_RING_FLAGS_MSI_SWAP,
!!(params.flags & HAL_SRNG_FLAGS_MSI_SWAP));
which might as well be written as
if (params.flags & HAL_SRNG_FLAGS_MSI_SWAP)
cmd->info1 |= HTT_SRNG_SETUP_CMD_INFO1_RING_FLAGS_MSI_SWAP;
(since info1 is fully initialized to start with), but in
a long chain of FIELD_PREP() this really seems fine.
However, it triggers a sparse warning, in the check in
the macro for whether a constant value fits into the mask,
as this contains a "& (_val)". In this case, this really
is always intentional, so just suppress the warning by
adding "0+" to the expression, indicating explicitly that
this is correct.

Currently when suspending driver and stopping workqueue it is checked whether
workqueue is not NULL and if so, it is destroyed.
Function destroy_workqueue() does drain queue and does clear variable, but
it does not set workqueue variable to NULL. This can cause kernel/module
panic if code attempts to clear workqueue that was not initialized.
This scenario is possible when resuming suspended driver in stmmac_resume(),
because there is no handling for failed stmmac_hw_setup(),
which can fail and return if DMA engine has failed to initialize,
and workqueue is initialized after DMA engine.
Should DMA engine fail to initialize, resume will proceed normally,
but interface won't work and TX queue will eventually timeout,
causing 'Reset adapter' error.
This then does destroy workqueue during reset process.
And since workqueue is initialized after DMA engine and can be skipped,
it will cause kernel/module panic.
To secure against this possible crash, set workqueue variable to NULL when
destroying workqueue.
Log/backtrace from crash goes as follows:

Updating link clock rate for different speeds is only needed when
using RGMII, as that mode requires changing clock speed when the link
speed changes. Let's restrict updating the link clock speed in
ethqos_update_link_clk() to just RGMII. Other modes such as SGMII
only need to enable the link clock (which is already done in probe).

====================
ioam6: netlink multicast event
v5:
- remove the "must be the destination" check before sending an ioam6
event
v4:
- rebase on top of net merge
v3:
- patchset was mistakenly superseded due to same cover title used for
iproute2-next equivalent patch -> resend (renamed)
v2:
- fix warnings
Add generic netlink multicast event support to ioam6 as another solution
to share IOAM data with user space. The other one being via IPv6 raw
sockets combined with ancillary data (or packet socket, if the listener
does not need the processing of the IOAM Option-Type, since the hook is
before in that case). This patchset focuses on the IOAM Pre-allocated
Trace (the only Option-Type currently supported in the kernel), and so
on IOAM "trace" events. See an example of a consumer here [1].

If we're processing an IOAM Pre-allocated Trace Option-Type (the only
one supported currently), then send the trace as an ioam6 event to the
netlink multicast group. This way, user space apps will be able to
collect IOAM data.

Add a multicast group to the ioam6 generic netlink family and provide
ioam6_event() to send an ioam6 event to the multicast group.

Add new api to support ioam6 events for generic netlink multicast. A
first "trace" event is added to the list of ioam6 events, which will
represent an IOAM Pre-allocated Trace Option-Type. It provides another
solution to share IOAM data with user space.

The drm_num_crtcs() helper determines the number of CRTCs by iterating
over the list of CRTCs that have been registered with the mode config.
However, we already keep track of that number in the mode config's
num_crtcs field, so we can simply retrieve the value from that and
remove the extra helper function.
