Use a plain BLK_MQ_F_* flag to select the round robin tag selection
instead of overlaying an enum with just two possible values into the
flags space.
Doing so allows adding a BLK_MQ_F_MAX sentinel for simplified overflow
checking in the messy debugfs helpers.

Constify the following API:
struct device *device_find_child(struct device *dev, void *data,
int (*match)(struct device *dev, void *data));
To :
struct device *device_find_child(struct device *dev, const void *data,
device_match_t match);
typedef int (*device_match_t)(struct device *dev, const void *data);
with the following reasons:
- Protect caller's match data @*data which is for comparison and lookup
and the API does not actually need to modify @*data.
- Make the API's parameters (@match)() and @data have the same type as
all of other device finding APIs (bus|class|driver)_find_device().
- All kinds of existing device match functions can be directly taken
as the API's argument, they were exported by driver core.
Constify the API and adapt for various existing usages.
BTW, various subsystem changes are squashed into this commit to meet
'git bisect' requirement, and this commit has the minimal and simplest
changes to complement squashing shortcoming, and that may bring extra
code improvement.

Add support to handle port channel RSCN.
Port channel RSCN is a Cisco vendor specific RSCN event. It is applicable
only to Cisco UCS fabrics. If there's a change in the port channel
configuration, an RCSN is sent to fnic. This is used to serially reset the
scsi initiator fnics so that there's no all paths down scenario. The
affected fnics are added to a list that are reset with a small time gap
between them.

The patches were cut against Martin's 6.14/scsi-queue tree.

Current lpfc bsg implementation allows a maximum fw read object size of
30KB. Implementation and support for read object mailbox commands for fw
objects larger than 30KB are now required for proprietary applications.
Thus, update the lpfc_sli_config_emb0_subsys structure and its associated
submission and completion paths to accommodate for an alternative form of
read object command that supports large fw objects.

When a LS_RJT is received with reason explanation authentication required,
current driver logic is to retry the PLOGI up to 48 times. In the worse
case scenario, 48 retries can take longer than dev_loss_tmo and if there is
an RSCN received indicating an authentication requirement change, the
driver may miss processing it. Fix by adding logic to specifically handle
reason explanation authentication required and set the max retry count to 8
times.

In lpfc_check_adisc, remove the requirement that the ndlp object must have
been RPI registered. Whether or not the ndlp is RPI registered is
unrelated to verifying that the received ADISC is intended for that ndlp
rport object.
After ADISC receipt, there's no need to put the ndlp state into NPR. Let
the cmpl routines from the actions taken earlier in ADISC handling set the
proper ndlp state.
Also, refactor when a RESUME_RPI mailbox command should be sent. It should
only be sent if the RPI registered flag is set.

Remove the NLP_TARGET_REMOVE flag as its usage is obsolete. The current
framework is to rely on the lpfc_dev_loss_tmo_callbk from upper layer to
notify final ndlp kref release. There's no need to specifically set
NLP_EVT_DEVICE_RM when a LOGO completes. The dev_loss_tmo_callbk is
responsible for the final kref put.

Currently, the code does:
if (x == 0) {
x &= ~0x3;
x |= 0x1;
}
Zeroing bits 0 and 1 of a variable that is 0 is not necessary. So directly
set the variable to 1.

Use the proper API instead of open coding it.
However it looks like qedi_percpu_io_thread() kthread could be replaced by
