Even when alx_setup_speed_duplex() is called, we still
need to call alx_cfg_mac_flowcontrol() and set hw->flowctrl
if flow control changed.
This was a bug I accidentally introduced while simplifying
the original driver.

When the firmware supports the UPDATE_QP command, if the VF link is disabled,
block all QPs opened by the VF, by programming the UPDATE_QP command to drop
all RX & TX traffic to/from these QPs. Operates only in VST mode.

Within VST mode, enable modifying the vlan and/or qos
for a VF without requiring unbind/rebind.
This requires firmware which supports the UPDATE_QP command.
(If the command is not available, we fall back to requiring
unbind/bind to activate these changes).
To avoid race conditions with modify-qp on QPs that are affected
by update-qp, this operation is performed on the comm_wq.
If the update operation succeeds for all the necessary QPs, a
vlan_unregister is performed for the abandoned vlan id.

Several InfiniBand HCAs allow configuring the completion vector per
CQ. This allows spreading the workload created by IB completion
interrupts over multiple MSI-X vectors and hence over multiple CPU
cores. In other words, configuring the completion vector properly not
only allows reducing latency on an initiator connected to multiple
SRP targets but also allows improving throughput.

An SRP target is required to maintain a single connection between
initiator and target. This means that if the 'add_target' attribute
is used to create a second connection to a target, the first
connection will be logged out and that the SCSI error handler will
kick in. The SCSI error handler will cause the SRP initiator to
reconnect, which will cause I/O over the second connection to fail.
Avoid such ping-pong behavior by disabling relogins.
If reconnecting manually is necessary, that is possible by deleting
and recreating an rport via sysfs.

Whenever a DASD request encounters a timeout we might
need to abort all outstanding requests on this or
even other devices.
This is especially useful if one wants to fail all
devices on one side of a RAID10 configuration, even
though only one device exhibited an error.
To handle this I've introduced a new device flag
DASD_FLAG_ABORTIO.
This flag is evaluated in __dasd_process_request_queue()
and will invoke blk_abort_request() for all
outstanding requests with DASD_CQR_FLAGS_FAILFAST set.
This will cause any of these requests to be aborted
immediately if the blk_timeout function is activated.
The DASD_FLAG_ABORTIO is also evaluated in
__dasd_process_request_queue to abort all
new request which would have the
DASD_CQR_FLAGS_FAILFAST bit set.
The flag can be set with the new ioctls 'BIODASDABORTIO'
and removed with 'BIODASDALLOWIO'.

The DASD driver is using FASTFAIL as an equivalent to the
transport errors in SCSI. And the 'steal lock' function maps
roughly to a reservation error. So we should be returning the

This patch implements generic block layer timeout handling
callbacks for DASDs. When the timeout expires the respective
cqr is aborted.
With this timeout handler time-critical request abort
is guaranteed as the abort does not depend on the internal
state of the various DASD driver queues.

Originally the DASD device tasklet would process the entries on
the ccw_queue until the first non-final request was found.
Which was okay as long as all requests have the same retries and
expires parameter.
However, as we're now allowing to modify both it is possible to
have requests _after_ the first request which already have expired.
So we need to check all requests in the device tasklet.

It is not preferable to have the allocated pages for carveout
memories freed before they are unmapped. The code that deals
with the cleanup of carveout memories is therefore moved after
the corresponding mapping entries were cleaned up.
This is mostly a no-op since the remote processors are already
stopped when the cleanup function is called, but this will make
the cleanup code follow the exact reverse path of allocation.

The GENERIC_PCI_IOMAP does not depend on CONFIG_PCI so move
it to the CONFIG_MIPS symbol so it's always selected for MIPS.
This fixes the missing pci_iomap declaration for MIPS.
Moreover, the pci_iounmap function was not defined in the
io.h header file if the CONFIG_PCI symbol is not set,
but it should since MIPS is not using CONFIG_GENERIC_IOMAP.
This fixes the following problem on a allyesconfig:
drivers/net/ethernet/3com/3c59x.c:1031:2: error: implicit declaration of
function 'pci_iomap' [-Werror=implicit-function-declaration]
