If FCoE is not configured, libfc/libfcoe keeps on retrying FLOGI and after
3 retries driver does a context reset and tries fipvlan again. This leads
to context reset message flooding the logs. Hence ratelimit the message to
prevent flooding the logs.

This series consists of the usual driver updates (ufs, smartpqi, lpfc,
target, megaraid_sas, hisi_sas, qla2xxx) and minor updates and bug
fixes. Notable core changes are the removal of scsi->tag which caused
some churn in obsolete drivers and a sweep through all drivers to call
scsi_done() directly instead of scsi->done() which removes a pointer
indirection from the hot path and a move to register core sysfs files
earlier, which means they're available to KOBJ_ADD processing, which
necessitates switching all drivers to using attribute groups.

This driver has some left over "return 1" on failure style code mixed with
"return negative error codes" style code. The caller doesn't care so we
should just convert everything to return negative error codes.
Then there was a problem that there were two variables used to store error
codes which just resulted in confusion. If qedf_alloc_bdq() returned a
negative error code, we accidentally returned success instead of
propagating the error code. So get rid of the "rc" variable and use
"status" every where.
Also remove the "status = 0" initialization so that these sorts of bugs
will be detected by the compiler in the future.

The MFW may make a call to qed and then to qedf for protocol statistics
while the function is still probing. If this happens it's possible that
some members of the struct qedf_ctx may not be fully initialized which can
result in a NULL pointer dereference or general protection fault.
To prevent this, add a new flag call QEDF_PROBING and set it when the
__qedf_probe() function is active. Then in the qedf_get_protocol_tlv_data()
function we can check if the function is still probing and return
immediantely before any uninitialized structures can be touched.

The original code used a for-loop that looped over each of the 8 bytes

Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI updates from James Bottomley:
"This is mostly update of the usual drivers: qla2xxx, ufs, smartpqi,
lpfc, hisi_sas, qedf, mpt3sas; plus a whole load of minor updates. The
only core change this time around is the addition of request batching
for virtio. Since batching requires an additional flag to use, it
should be invisible to the rest of the drivers"

There is a race b/w fipvlan request and response path:
=====
qedf_fcoe_process_vlan_resp:113]:2: VLAN response, vid=0xffd.
qedf_initiate_fipvlan_req:165]:2: vlan = 0x6ffd already set.
qedf_set_vlan_id:139]:2: Setting vlan_id=0ffd prio=3.
======
The request thread sees that vlan is already set and fails to call
ctrl_link_up.
Fix:
- While setting vlan_id use local variable and before setting vlan_id.
- Call fcoe_ctlr_link_up in next iteration of fipvlan request.

The list of rports might become stale so we should rather traverse the
discovery list when trying relogin.

Driver was wrongly interpreting the supported cap value returned by qed.
Solution: Use QED define macros instead of OS defined for interpreting
supporting speeds.

- On some setups fipvlan can be retried for long duration and the
connection to switch was not there so it was not getting any reply.
- During unload this thread was hanging.
Problem Resolution:
Check if unload is in progress, then quit from fipvlan thread.
