Always receive the full immediate data buffer such that the iSCSI target driver does not attempt to parse immediate data as an iSCSI PDU. Note: the current code base only calls iscsit_get_dataout() if the size of the immediate data buffer does not exceed the buffer size derived from the SCSI CDB. See also target_cmd_size_check().

As such, for when the link is lost for a root PHY attached to an expander PHY, we get no broadcast event. This causes an issue for libsas, in that we will not revalidate the domain for these events. As a solution, for when a root PHY is formed or deformed from a root port, insert a broadcast event to trigger a domain revalidation. Signed-off-by: John Garry Signed-off-by: Martin K.
