Some FC adapters from Marvell offer the ability to encrypt data in flight

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.

Some FC adapters from Marvell offer the ability to encrypt data in flight
(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.

In case of success, application will use the QL_VND_SC_AUTH_OK BSG call to

In case of failure, application will use the QL_VND_SC_AUTH_FAIL bsg call
to tell driver to tear down the connection and retry. In the case where an
existing session is active, the re-key process can fail. The session tear
down ensures data is not further compromised.

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.

For SD card reader devices that have the BLIST_IGN_MEDIA_CHANGE flag
set, a MEDIUM MAY HAVE CHANGED unit attention is established after
resuming from runtime suspend. Send a REQUEST SENSE to consume the UA.

The "downside" is that for these devices we now rely on users to not
change the medium (SD card) *during* a runtime suspend/resume cycle,
i.e. when not unmounting.

To enable runtime PM for an SD cardreader (device number 0:0:0:0), do:

echo 0 > /sys/module/block/parameters/events_dfl_poll_msecs

Use the scsi_get_lba() helper instead of a function internal to the
SCSI disk driver. Remove #include "sd.h".

scsi_get_lba() confusingly returned the block layer sector number expressed
in units of 512 bytes. Now that we have a more aptly named
scsi_get_sector() function, make scsi_get_lba() return the actual LBA.

Use scsi_get_sector() instead of scsi_get_lba() since the name of the
latter is confusing. This patch does not change any functionality.

Since scsi_get_lba() returns a sector_t value instead of the LBA, the name
of that function is confusing. Introduce an identical function
scsi_get_sector().
