If netdev_mc_count() is not zero and not IFF_ALLMULTI, filter
incoming multicast packets. The chip has a Multicast Address Hash Table
for allowed multicast addresses, so we fill it.
Implement .ndo_set_rx_mode and recalculate multicast hash table. Also
observe change of IFF_PROMISC and IFF_ALLMULTI netdev flags.

When gso.hdr_len is zero and a packet is transmitted via write() or
writev(), all payload is treated as header which requires a contiguous
memory allocation. This allocation request is harder to satisfy, and may
even fail if there is enough fragmentation.
Note that sendmsg() code path limits the linear copy length, so this change
makes write()/writev() and sendmsg() paths more consistent.

When the netdev trigger is activates, it tries to determine what
device the LED blinks for, and what the current blink mode is.
The documentation for hw_control_get() says:
* Return 0 on success, a negative error number on failing parsing the
* initial mode. Error from this function is NOT FATAL as the device
* may be in a not supported initial state by the attached LED trigger.
*/
For the Marvell PHY and the Armada 370-rd board, the initial LED blink
mode is not supported by the trigger, so it returns an error. This
resulted in not getting the device the LED is blinking for. As a
result, the device is unknown and offloaded is never performed.
Change to condition to always get the device if offloading is
supported, and reduce the scope of testing for an error from
hw_control_get() to skip setting trigger internal state if there is an
error.

When using a fixed-link setup, certain devices like the SJA1105 require a
small pause in the TXC clock line to enable their internal tunable
delay line (TDL).
To satisfy this requirement, this patch temporarily disables the TX clock,
and restarts it after a required period. This provides the required
silent interval on the clock line for SJA1105 to complete the frequency
transition and enable the internal TDLs. This action occurs before the link
is built up, so it does not impact a normal device too. There is no
need to identify if the connected device is an SJA1105 alike or not during
the implementation.
So far we have only enabled this feature on the i.MX93 platform.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert the mediatek drm drivers from always returning zero in
the remove callback to the void returning variant.

This was not strictly necessary, as page unpinning (ie. shrinker) only
cares about the resv. It did give us some extra sanity checking for
userspace controlled iova, and was useful to catch issues on kernel and
userspace side when enabling userspace iova. But if userspace screws
this up, it just corrupts it's own gpu buffers and/or gets iova faults.
So we can just let userspace shoot it's own foot and drop the extra per-

If we repeatedly fail to fake offline memory to unplug it, we won't be
sending any unplug requests to the device. However, we only check if the
config changed when sending such (un)plug requests.
We could end up trying for a long time to unplug memory, even though
the config changed already and we're not supposed to unplug memory
anymore. For example, the hypervisor might detect a low-memory situation
while unplugging memory and decide to replug some memory. Continuing
trying to unplug memory in that case can be problematic.
So let's check on a more regular basis.

Mode (SBM)
In case offline_and_remove_memory() fails in SBM, we leave a completely
unplugged Linux memory block stick around until we try plugging memory
again. We won't try removing that memory block again.
offline_and_remove_memory() may, for example, fail if we're racing with
another alloc_contig_range() user, if allocating temporary memory fails,
or if some memory notifier rejected the offlining request.
Let's handle that case better, by simple retrying to offline and remove
such memory.

When "unsafe unplug" is enabled, we don't fake-offline all memory ahead of
actual memory offlining using alloc_contig_range(). Instead, we rely on
offline_pages() to also perform actual page migration, which might fail
or take a very long time.
In that case, it's possible to easily run into endless loops that cannot be
aborted anymore (as offlining is triggered by a workqueue then): For
example, a single (accidentally) permanently unmovable page in
ZONE_MOVABLE results in an endless loop. For ZONE_NORMAL, races between
isolating the pageblock (and checking for unmovable pages) and
concurrent page allocation are possible and similarly result in endless
loops.
The idea of the unsafe unplug mode was to make it possible to more
reliably unplug large memory blocks. However, (a) we really should be
tackling that differently, by extending the alloc_contig_range()-based
mechanism; and (b) this mode is not the default and as far as I know,
it's unused either way.
So let's simply get rid of it.

We were allocating irq vectors at the time the aux dev was probed,
but that is before the PCI VF is assigned to a separate iommu domain
by vhost_vdpa. Because vhost_vdpa later changes the iommu domain the
interrupts do not work.
Instead, we can allocate the irq vectors later when we see DRIVER_OK and
know that the reassignment of the PCI VF to an iommu domain has already
happened.

Our driver sets a mac if the HW is 00:..:00 so we need to be sure to
advertise VIRTIO_NET_F_MAC even if the HW doesn't. We also need to be
sure that virtio_net sees the VIRTIO_NET_F_MAC and doesn't rewrite the
mac address that a user may have set with the vdpa utility.
After reading the hw_feature bits, add the VIRTIO_NET_F_MAC to the driver's
supported_features and use that for reporting what is available. If the
HW is not advertising it, be sure to strip the VIRTIO_NET_F_MAC before
finishing the feature negotiation. If the user specifies a device_features
bitpattern in the vdpa utility without the VIRTIO_NET_F_MAC set, then
don't set the mac.

Kernel uses `struct virtio_net_ctrl_rss` to save command-specific-data
for both the VIRTIO_NET_CTRL_MQ_HASH_CONFIG and
VIRTIO_NET_CTRL_MQ_RSS_CONFIG commands.
According to the VirtIO standard, "Field reserved MUST contain zeroes.
It is defined to make the structure to match the layout of
virtio_net_rss_config structure, defined in 5.1.6.5.7.".
Yet for the VIRTIO_NET_CTRL_MQ_HASH_CONFIG command case, the `max_tx_vq`
field in struct virtio_net_ctrl_rss, which corresponds to the
`reserved` field in struct virtio_net_hash_config, is not zeroed,
thereby violating the VirtIO standard.
This patch solves this problem by zeroing this field in
virtnet_init_default_rss().

Pull networking fixes from Jakub Kicinski:
"Including fixes from netfilter, wireless and bpf.
Still trending up in size but the good news is that the "current"
regressions are resolved, AFAIK.
We're getting weirdly many fixes for Wake-on-LAN and suspend/resume
handling on embedded this week (most not merged yet), not sure why.
But those are all for older bugs.
Current release - regressions:
- tls: set MSG_SPLICE_PAGES consistently when handing encrypted data
over to TCP
Current release - new code bugs:
- eth: mlx5: correct IDs on VFs internal to the device (IPU)
Previous releases - regressions:
- phy: at803x: fix WoL support / reporting on AR8032
- bonding: fix incorrect deletion of ETH_P_8021AD protocol VID from
slaves, leading to BUG_ON()
- tun: prevent tun_build_skb() from exceeding the packet size limit
- wifi: rtw89: fix 8852AE disconnection caused by RX full flags
- eth/PCI: enetc: fix probing after 6fffbc7ae137 ("PCI: Honor
firmware's device disabled status"), keep PCI devices around even
if they are disabled / not going to be probed to be able to apply
quirks on them
- eth: prestera: fix handling IPv4 routes with nexthop IDs
Previous releases - always broken:
- netfilter: re-work garbage collection to avoid races between
user-facing API and timeouts
- tunnels: fix generating ipv4 PMTU error on non-linear skbs
- nexthop: fix infinite nexthop bucket dump when using maximum
nexthop ID
- wifi: nl80211: fix integer overflow in nl80211_parse_mbssid_elems()
Misc:
- unix: use consistent error code in SO_PEERPIDFD
- ipv6: adjust ndisc_is_useropt() to include PREFIX_INFO, in prep for
upcoming IETF RFC"

The ndev was accessed on shutdown without a check if it actually exists.
This triggered the crash pasted below.
Instead of doing the ndev check, delete the shutdown handler altogether.
The irqs will be released at the parent VF level (mlx5_core).

mlx5_vdpa_destroy_mr can be called from .set_map with data ASID after
the control virtqueue ASID iotlb has been populated. The control vq
iotlb must not be cleared, since it will not be populated again.
So call the ASID aware destroy function which makes sure that the
right vq resource is destroyed.
