packets. This keeps the host and device synchronized and prevents xruns.

drm/xe/pf: Set VF LMEM BAR size
LMEM is partitioned between multiple VFs and we expect that the more
VFs we have, the less LMEM is assigned to each VF.
This means that we can achieve full LMEM BAR access without the need to
attempt full VF LMEM BAR resize via pci_resize_resource().
Always try to set the largest possible BAR size that allows to fit the
number of enabled VFs and inform the user in case the resize attempt is
not successful.

ata: libata-scsi: Fix CDL control
Delete extra checks for the ATA_DFLAG_CDL_ENABLED flag that prevent
SET FEATURES command from being issued to a drive when NCQ commands
are active.
ata_mselect_control_ata_feature() sets / clears the ATA_DFLAG_CDL_ENABLED
flag during the translation of MODE SELECT to SET FEATURES. If SET FEATURES
gets deferred due to outstanding NCQ commands, the original MODE SELECT
command will be re-queued. When the re-queued MODE SELECT goes through
the ata_mselect_control_ata_feature() translation again, SET FEATURES
will not be issued because ATA_DFLAG_CDL_ENABLED has been already set or
cleared by the initial translation of MODE SELECT.
The ATA_DFLAG_CDL_ENABLED checks in ata_mselect_control_ata_feature()
are safe to remove because scsi_cdl_enable() implements a similar logic
that avoids enabling CDL if it has been enabled already.

ata: libata-eh: Fix link state check for IDE/PATA ports
Commit 4371fe1ba400 ("ata: libata-eh: Avoid unnecessary resets when
revalidating devices") replaced the call to ata_phys_link_offline() in
ata_eh_revalidate_and_attach() with the new function
ata_eh_link_established() which relaxes the checks on a device link
state to account for low power mode transitions. However, this change
assumed that the device port has a valid scr_read method to obtain the
SStatus register for the port. This is not always the case, especially
with older IDE/PATA adapters (e.g. PATA/IDE devices emulated with QEMU).
For such adapter, ata_eh_link_established() will always return false,
causing ata_eh_revalidate_and_attach() to go into its error path and
ultimately to the device being disabled.
Avoid this by restoring the previous behavior, which is to assume that
the link is online if reading the port SStatus register fails.
While at it, also fix the spelling of SStatus in the comment describing
the function ata_eh_link_established().

net: usb: asix_devices: add phy_mask for ax88772 mdio bus
Without setting phy_mask for ax88772 mdio bus, current driver may create
at most 32 mdio phy devices with phy address range from 0x00 ~ 0x1f.
DLink DUB-E100 H/W Ver B1 is such a device. However, only one main phy
device will bind to net phy driver. This is creating issue during system
suspend/resume since phy_polling_mode() in phy_state_machine() will
directly deference member of phydev->drv for non-main phy devices. Then
NULL pointer dereference issue will occur. Due to only external phy or
internal phy is necessary, add phy_mask for ax88772 mdio bus to workarnoud
the issue.

net: kcm: Fix race condition in kcm_unattach()
syzbot found a race condition when kcm_unattach(psock)
and kcm_release(kcm) are executed at the same time.
kcm_unattach() is missing a check of the flag
kcm->tx_stopped before calling queue_work().
If the kcm has a reserved psock, kcm_unattach() might get executed
between cancel_work_sync() and unreserve_psock() in kcm_release(),
requeuing kcm->tx_work right before kcm gets freed in kcm_done().
Remove kcm->tx_stopped and replace it by the less
error-prone disable_work_sync().

net/sched: ets: use old 'nbands' while purging unused classes
Shuang reported sch_ets test-case [1] crashing in ets_class_qlen_notify()
after recent changes from Lion [2]. The problem is: in ets_qdisc_change()
we purge unused DWRR queues; the value of 'q->nbands' is the new one, and
the cleanup should be done with the old one. The problem is here since my
first attempts to fix ets_qdisc_change(), but it surfaced again after the
recent qdisc len accounting fixes. Fix it purging idle DWRR queues before
assigning a new value of 'q->nbands', so that all purge operations find a
consistent configuration:
- old 'q->nbands' because it's needed by ets_class_find()
- old 'q->nstrict' because it's needed by ets_class_is_strict()
Jedrzej adds option to skip phys_port_name generation and opts
ixgbe into it as some configurations rely on pre-devlink naming
which could end up broken as a result.
