cachable and mmkey.rb_key together are used by mlx5_revoke_mr() to put the
MR/mkey back into the cache. In all cases they should be set correctly.
alloc_cacheable_mr() was setting cachable but not filling rb_key,
resulting in cache_ent_find_and_store() bucketing them all into a 0 length
entry.
implicit_get_child_mr()/mlx5_ib_alloc_implicit_mr() failed to set cachable
or rb_key at all, so the cache was not working at all for implicit ODP.

When a cache ent already exists but doesn't have any mkeys in it the cache
will automatically create a new one based on the specification in the

ent->ats was missed when creating the new key and so ma_translation_mode

Adding/updating VSI list rule, as well as allocating/freeing VSI list
resource are called several times with type ICE_SW_LKUP_LAST, which fails
because ice_update_vsi_list_rule() and ice_aq_alloc_free_vsi_list()

Commit under Fixes optimized the number of recv() calls
needed during RTM_GETROUTE dumps, but we got multiple
reports of applications hanging on recv() calls.
Applications expect that a route dump will be terminated
with a recv() reading an individual NLM_DONE message.
Coalescing NLM_DONE is perfectly legal in netlink,
but even tho reporters fixed the code in respective
projects, chances are it will take time for those
applications to get updated. So revert to old behavior
(for now)?
This is an IPv6 version of commit 460b0d33cf10 ("inet: bring

virtio_net: fixes for checksum offloading and XDP handling
This series of patches aim to address two specific issues identified
in the virtio_net driver related to checksum offloading and XDP
processing of fully checksummed packets.
The first patch corrects the handling of checksum offloading in the
driver. The second patch addresses an issue where the XDP program had
no trouble with fully checksummed packets.
====================

The XDP program can't correctly handle partially checksummed
packets, but works fine with fully checksummed packets. If the
device has already validated fully checksummed packets, then
the driver doesn't need to re-validate them, saving CPU resources.
Additionally, the driver does not drop all partially checksummed
packets when VIRTIO_NET_F_GUEST_CSUM is not negotiated. This is
not a bug, as the driver has always done this.

In virtio spec 0.95, VIRTIO_NET_F_GUEST_CSUM was designed to handle
partially checksummed packets, and the validation of fully checksummed
packets by the device is independent of VIRTIO_NET_F_GUEST_CSUM
negotiation. However, the specification erroneously stated:
"If VIRTIO_NET_F_GUEST_CSUM is not negotiated, the device MUST set flags
to zero and SHOULD supply a fully checksummed packet to the driver."
This statement is inaccurate because even without VIRTIO_NET_F_GUEST_CSUM
negotiation, the device can still set the VIRTIO_NET_HDR_F_DATA_VALID flag.
Essentially, the device can facilitate the validation of these packets'
checksums - a process known as RX checksum offloading - removing the need
for the driver to do so.
This scenario is currently not implemented in the driver and requires
correction. The necessary specification correction[1] has been made and
approved in the virtio TC vote.

After ecf848eb934b ("net: usb: ax88179_178a: fix link status when link is
set to down/up") to not reset from usbnet_open after the reset from
usbnet_probe at initialization stage to speed up this, some issues have
been reported.
It seems to happen that if the initialization is slower, and some time
passes between the probe operation and the open operation, the second reset
from open is necessary too to have the device working. The reason is that
if there is no activity with the phy, this is "disconnected".
In order to improve this, the solution is to detect when the phy is
"disconnected", and we can use the phy status register for this. So we will
only reset the device from reset operation in this situation, that is, only
if necessary.
The same bahavior is happening when the device is stopped (link set to
down) and later is restarted (link set to up), so if the phy keeps working
we only need to enable the mac again, but if enough time passes between the
device stop and restart, reset is necessary, and we can detect the
situation checking the phy status register too.
