FC and iSCSI class set SCSI devices to transport-offline state after
fast_io_fail/replacement_timeout has fired, but after relogin, function
scsi_internal_device_unblock() is not setting scsi device state to running.
Due to this the devices even after being relogged in remain offline.

In qla4xxx_ep_connect(), qla_ep->dst_addr and dst_addr are type
struct sockaddr. We are copying sizeof(struct sockaddr_in6) bytes
from dst_addr to qla_ep->dst_addr which is 12 bytes larger. This
will cause memory corruption. So we change qla_ep->dst_addr to
struct sockaddr_storage which is of 128 byte, large enough to
hold sizeof(struct sockaddr_in6).

It turns out Smart Array logical drives do not support target
reset and when the target reset fails, the logical drive will
be taken off line. Symptoms look like this:
hpsa 0000:03:00.0: Abort request on C1:B0:T0:L0
hpsa 0000:03:00.0: resetting device 1:0:0:0
hpsa 0000:03:00.0: cp ffff880037c56000 is reported invalid (probably means target device no longer present)
hpsa 0000:03:00.0: resetting device failed.
sd 1:0:0:0: Device offlined - not ready after error recovery
sd 1:0:0:0: rejecting I/O to offline device
EXT3-fs error (device sdb1): read_block_bitmap:
LUN reset is supported though, and is what we should be using.
Target reset is also disruptive in shared SAS situations,
for example, an external MSA1210m which does support target
reset attached to Smart Arrays in multiple hosts -- a target
reset from one host is disruptive to other hosts as all LUNs
on the target will be reset and will abort all outstanding i/os
back to all the attached hosts. So we should use LUN reset,
not target reset.
Tested this with Smart Array logical drives and with tape drives.
Not sure how this bug survived since 2009, except it must be very
rare for a Smart Array to require more than 30s to complete a request.

When device discovery is disabled during driver load time using module
parameter "disable_discovery=1" and when diag reset is issued then from logs,
it is observed that the devices get added, removed and then added with new
target ids.
So, in order to limit this turn-off the code which is deleting and devices

A new sysfs shost attribute called "BMR_status" is implemented to
report Backup Rail Monitor status.
This attribute is located in the path
/sys/class/scsi_host/host#/BMR_status
when reading this adapter attribute, then driver will output the state
of GPIO[24]. It returns "0" if BMR is healthy and it returns "1" for failure.
if it returns an empty string then it means that there was an error while
obtaining the BMR status. Then check dmesg for what error has occured.

libsas and ipr pass flags to ata_host_init that are meant for the port.
ata_host flags:
ATA_HOST_SIMPLEX = (1 << 0), /* Host is simplex, one DMA channel per host only */
ATA_HOST_STARTED = (1 << 1), /* Host started */
ATA_HOST_PARALLEL_SCAN = (1 << 2), /* Ports on this host can be scanned in parallel */
ATA_HOST_IGNORE_ATA = (1 << 3), /* Ignore ATA devices on this host. */
flags passed by libsas:
ATA_FLAG_SATA = (1 << 1),
ATA_FLAG_PIO_DMA = (1 << 7), /* PIO cmds via DMA */
ATA_FLAG_NCQ = (1 << 10), /* host supports NCQ */
The only one that aliases is ATA_HOST_STARTED which is a 'don't care' in
the libsas and ipr cases since ata_hosts from these sources are not
registered with libata.
