For target port that register itself as both FCP + NVMe, initiator driver
will try to login one mode at a time. If the last mode did not succeed,
then driver will try the other mode.
When error is encountered, current code only flip to other mode one time
(NVMe->FCP) and remain on the last mode. Driver wrongly assumed target
port does not support PRLI NVMe, instead it was not ready to receive PRLI.
This patch will alternate back and forth on every PRLI failure until login
retry count has depleted or it is succeeded.

During runtime, driver and authentication application need to stay in sync
in terms of: Session being down|up, arrival of new authentication
message (AUTH ELS) and SADB update completion.
These events are queued up as doorbell to the authentication
application. Application would read this doorbell on regular basis to stay
up to date. Each SCSI host would have a separate doorbell queue.
The doorbell interface can daisy chain a list of events for each read. Each
event contains an event code + hint to help application steer the next
course of action.

(EDIF). This feature requires an application to act as an authenticator.
There is no FC switch scan service that can indicate whether a device is
secure or non-secure.
In order to detect whether the remote port supports encrypted operation,
driver must first do a PLOGI with the remote device. On completion of the
PLOGI, driver will query firmware to see if the device supports secure
login. To do that, driver + firmware must advertise the security bit via
PLOGI's service parameter. The remote device shall respond using the same
service parameter whether it supports it or not.

Some FC adapters from Marvell offer the ability to encrypt data in flight
(EDIF). This feature requires an application to act as an authenticator.
As part of the authentication process, the authentication application will
generate a SADB entry (Security Association/SA, key, SPI value, etc). This
SADB is then passed to driver to be programmed into hardware. There will be
a pair of SADB's (Tx and Rx) for each connection.
After some period, the application can choose to change the key. At that
time, a new set of SADB pair is given to driver. The old set of SADB will
be deleted.
Add a new bsg call (QL_VND_SC_SA_UPDATE) to allow application to allow
adding or deleting SADB entries. Driver will not keep the key in
memory. It will pass it to HW.
It is assumed that application will assign a unique SPI value to this SADB
(SA + key). Driver + hardware will assign a handle to track this unique
SPI/SADB.

qla83xx_wait_logic() is used to control the frequency of device IDC lock
retries. If in_interrupt() is true, it does 20 loops of cpu_relax().
Otherwise, it sleeps for 100ms and yields the CPU.
While in_interrupt() is ill-defined and does not provide what the name
suggests, it is not needed here: that qla83xx_wait_logic() is exclusively
called by qla83xx_idc_lock() / unlock(), and they always run from process
context. Below is an analysis of all the idc lock/unlock callers, in order
of appearance:
- qla_os.c:
qla83xx_nic_core_unrecoverable_work(),
qla83xx_idc_state_handler_work(),
qla83xx_nic_core_reset_work(),
qla83xx_service_idc_aen(), all workqueue context
- qla_os.c: qla83xx_check_nic_core_fw_alive(), has msleep()
- qla_os.c: qla83xx_set_drv_presence(), called once from
qla2x00_abort_isp(), which is bound to process-context ->abort_isp()
hook. It also invokes wait_for_completion_timeout() through the chain
qla2x00_configure_hba() => qla24xx_link_initialize() =>
qla2x00_mailbox_command().
- qla_os.c: qla83xx_clear_drv_presence(), which is called from
qla2x00_abort_isp() discussed above, and from qla2x00_remove_one()
which is PCI process-context ->remove() hook.
- qla_os.c: qla83xx_need_reset_handler(), has a one second msleep() in
a loop.
- qla_os.c: qla83xx_device_bootstrap(), called only by
qla83xx_idc_state_handler(), which has multiple msleep()
invocations.
- qla_os.c: qla83xx_idc_state_handler(), multiple msleep()
invocations.
- qla_attr.c: qla2x00_sysfs_write_reset(), sysfs bin_attribute
->write() hook, process context
- qla_init.c: qla83xx_nic_core_fw_load()
=> qla_init.c: qla2x00_initialize_adapter()
=> bound to isp_operations ->initialize_adapter() hook
** => qla_os.c: qla2x00_probe_one(), PCI ->probe() process ctx
- qla_init.c: qla83xx_initiating_reset(), msleep() in a loop.
- qla_init.c: qla83xx_nic_core_reset(), called by
qla83xx_nic_core_reset_work(), workqueue context.
Remove the in_interrupt() check, and thus replace the entirety of
qla83xx_wait_logic() with an msleep(QLA83XX_WAIT_LOGIC_MS).
Mark qla83xx_idc_lock() / unlock() with "Context: task, can sleep".

Driver was using a shorter timeout waiting for PLOGI from the peer in
point-to-point configurations. Some devices takes some time (~4 seconds) to
initiate the PLOGI. This peer initiating PLOGI is when the peer has a
higher P-WWN.
Increase the wait time based on N2N R_A_TOV.

Current code uses wrong mailbox option to extract bbc from firmware. This
field is nested inside of PLOGI payload. Extract bbc from PLOGI template
payload.

BIT_13 of extended FW attribute informs about NVMe-2 support. Set BIT_15
of special feature control block for enabling SLER in FW. Set bit 8 (SLER
supported) to 1 for the service parameter information when sending NVMe
PRLI request. Set BIT_14 of special feature control block for enabling PI
Control in FW. Driver should set bit 9 (PI Control supported) to 1 for the
service parameter information when sending NVMe PRLI request. Set BIT_13
for NVMe Async events.

This patch tracks number of IOCB resources used in the I/O fast path. If
the number of used IOCBs reach a high water limit, driver would return the
I/O as busy and let upper layer retry. This prevents over subscription of
IOCB resources where any future error recovery command is unable to cut
through. Enable IOCB throttling by default.
