Udev uses the connection's persistent address/port in the
/dev/disk/by-path name. qla4xxx is not exporting this value
so its iscsi disk names have been lacking the iscsi info.
In the old driver we did not have this information but
we do now and can fix this by just setting the flags to tell
libiscsi/scsi_transport_iscsi to export this info in sysfs.

If an adapter dump times out, the ipr driver will abort the
dump and proceed to reset and recover the adapter. When an
adapter dump completes, the work thread which is reading the
adapter dump will initiate an adapter reset to recover the
adapter. However, when the adapter dump gets aborted, the
work thread should not initiate an adapter reset, since an
adapter reset is already in progress. This fixes a case of
calling pci_block_user_cfg_access overlapped, which results
in a BUG.

The following patch for megaraid_sas will fix a potential bad pointer access
in megasas_reset_timer(), when a MegaRAID 9265/9285 or 9360/9380 gets a
timeout. megasas_build_io_fusion() sets SCp.ptr to be a struct
megasas_cmd_fusion *, but then megasas_reset_timer() was casting SCp.ptr to be
a struct megasas_cmd *, then trying to access cmd->instance, which is invalid.
Just loading instance from scmd->device->host->hostdata in
megasas_reset_timer() fixes the issue.

This is just a cleanup, to silence static checker warnings. It
doesn't change how the code works.
buf[] can either be BUF_SIZE if this is called from sysfs, or it can
be 16 if it's called from aac_get_adapter_info() via
aac_get_serial_number(). We use the smaller limit here.
sizeof(dev->supplement_adapter_info.MfgPcbaSerialNo) is 12 so there

Firmware reserves DDBs if there are entries in the FLASH.
So there are no free DDBs left when a iSCSI login is initiated
by user space tool like iscsiadm.
Since now login is not controlled by firmware, LLD need to free

QLogic applications store the CHAP information in FLASH. During login,
authentication information is provided using an index into the CHAP region.
In order to support QLogic applications along with iscsiadm, updated the
LLD to not add duplicate CHAP entries in the CHAP region and preserve the
existing CHAP info in the CHAP region in FLASH.
This allows QLogic applications to pre-write the CHAP entries in the
CHAP region.
With iscsiadm, when the CHAP authentication information is sent to the LLD, the
LLD searches for the entry in CHAP region in FLASH, if exists then do not add.
If CHAP entry does not exist then add the CHAP entry in the CHAP region.

To download and flash the new images takes more than 15 minutes, so increase

The FPGA and flash back DRAM images don't have the same card_type as the IOA FW
