If recovery is triggered in presence of pending asynchronous
deliveries of storage blocks we do a forced cleanup after

In case there are no system resources to run a recovery we have to clear

The NETIUCV device driver allows to connect a Linux guest on z/VM to
another z/VM guest based on the z/VM communication facility IUCV.
Multiple output paths to different guests are possible, as well as
multiple input paths from different guests.
With this feature, you can configure multiple point-to-point NETIUCV
interfaces between your Linux on System z instance and another z/VM
guest.Signed-off-by: Ursula Braun

module_param(bool) used to counter-intuitively take an int. In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.It's time to remove the int/unsigned int option. For this version
it'll simply give a warning, but it'll break next kernel version.(Thanks to Joe Perches for suggesting coccinelle for 0/1 -> true/false).

This patch adds the ethtool callbacks necessary to change the rss
indirection table from userspace. Should the number of interrupts
change (e.g. across a close / open call, or through a reset) and
any one of the indirection table values fall out-of-range, the driver
will reset the indirection table to a default layout.[Integrated many suggestions made by Ben Hutchings.]

New FW can give clues to driver regarding default port type
and whether or not we should default to link sensing on the port.2 bits are added to QUERY_PORT command:
1. suggested_type: This bit gives a hint whether the default port type should be
IB or Ethernet.
The driver will use this hint in case the user didn't specify explicitly the link layer
type he wants to set.
2. default_sense: If this bit is set, we would sense the port type on start-up
and default the port to link sensingSigned-off-by: Yevgeny Petrilin

For ConnectX3 devices, we allow link sensing only if FW explicitly
