Pull SCSI updates from James Bottomley:
"This is mostly updates to the usual drivers: ufs, qedf, mpt3sas, lpfc,
xfcp, hisi_sas, cxlflash, qla2xxx.
In the absence of Nic, we're also taking target updates which are
mostly minor except for the tcmu refactor.
The only real core change to worry about is the removal of high page
bouncing (in sas, storvsc and iscsi). This has been well tested and no
problems have shown up so far"

This patch adds driver changes for supporting the Unified Fabric Port
(UFP). This is a new paritioning mode wherein MFW provides the set of
parameters to be used by the device such as traffic class, outer-vlan
tag value, priority type etc. Drivers receives this info via notifications
from mfw and configures the hardware accordingly.

Currently in the driver the qedf_ctx attribute vlan_hw_insert is used to
which whether to insert a VLAN tag in FIP frames (except for FIP VLAN
request which is explicitly sent out untagged at least from the driver's
point of view).
When we receive a FIP VLAN response, we set qedf->vlan_hw_insert to 0 which
makes the qedf_fip_send function insert the VLAN. However when we exhaust
our FIP VLAN retries, we do not set qedf->vlan_hw_insert to 0 which means
that the driver will not tag the FIP frame with the correct VLAN ID. The
result that was observed on the wire is that some entity either in the LL2
or L2 firmware is adding a NULL VLAN tag which can cause FIP solicitation
to fail.
The offload FCoE frame function, qedf_xmit, does not use the vlan_hw_insert
attribute to decide whether to tag frames with the FIP/FCoE VLAN. Instead
it unilaterially tags the offload frames with the VLAN ID stored in
qedf->vlan_id. This is the correct behavior so the driver can guarantee
that non-offload FIP frames go out with the correct VLAN ID.
Also use the Linux network layer helpers instead of doing the VLAN insert
manually.
Also fix setting the fallback VLAN so that it used the module parameter and
is not hardcoded to 1002 (though 1002 is the default).
[mkp: fixed typo]

is available.
Currently in the driver we've been using the fc_fcoe_set_mac() function to
set the source MAC for FCoE traffic. This works well in most cases as it
uses the spec. default FCF-MAC. However, if the administrator changes the
FCF-MAC switch, then any FCoE traffic we send will be dropped by the
switch.
Instead we should check the granted MAC from the FLOGI payload and use that
address if it is present. Otherwise, fall back to using the the default
FCF-MAC and the fabric ID of the port as the FCoE MAC address.
Once this address is known we need to set it when doing non-offload
traffic, offload traffic and setting the data_src_address libfcoe uses for
FIP keep alive messages.

It seems like a historic accident that these return unsigned char *,
and in many places that means casts are required, more often than not.
Make these functions return void * and remove all the casts across
the tree, adding a (u8 *) cast only where the unsigned char pointer
was used directly, all done with the following spatch:
@@
expression SKB, LEN;
typedef u8;
identifier fn = { skb_push, __skb_push, skb_push_rcsum };
@@
- *(fn(SKB, LEN))
+ *(u8 *)fn(SKB, LEN)
@@
expression E, SKB, LEN;
identifier fn = { skb_push, __skb_push, skb_push_rcsum };
type T;
@@
- E = ((T *)(fn(SKB, LEN)))
+ E = fn(SKB, LEN)
@@
expression SKB, LEN;
identifier fn = { skb_push, __skb_push, skb_push_rcsum };
@@
- fn(SKB, LEN)[0]
+ *(u8 *)fn(SKB, LEN)
Note that the last part there converts from push(...)[0] to the
more idiomatic *(u8 *)push(...).

If there are multiple descriptors for a particular type in a clear virtual
link we receive, we will not process it correctly but rather take the last
value. This can cause us not to not flap the virtual link as the value from
the descriptors that we compare against the our stored FCF or fc_lport values
may not match.
Change this to do a comparison when processing the each descriptor instead of at
the end and then set a bool if we need to do the reset.

We need to initialize qedf->fipvlan_compl in __qedf_probe so that if we
receive an unsolicited FIP VLAN response, the system doesn't crash due
to trying to complete an uninitialized completion.
Also add a check to see if there are any waiters on the completion so we
don't inadvertantly kick start the discovery process due to the
unsolicited frame.
Fixed the crash:
