Make the SCSI device identification page (83h) EUI-64 and NAA
IDs configurable. If neither the eui64_id nor the naa_id sysfs
attribute has been set, export the first eight bytes of the
t10_dev_id as an EUI-64 ID. If the NAA ID but not the EUI-64 ID
has been set, report the NAA ID only. If both IDs have been set,
report both.

Allow a set of completion vectors to be associated with each InfiniBand
HCA port and allocate the completion vector for each session in a
round-robin fashion from the per-port set. This helps to spread the
InfiniBand interrupt workload over multiple CPU's, at least if different
InfiniBand MSI-X vectors are associated with different CPU's.

When unloading the ib_srpt kernel module, instead of waiting until
all connected queue pairs have left the TimeWait state, destroy
these queue pairs immediately.

Coverity warns that 'handle == Q2T_SKIP_HANDLE' can never occur, because
code preceding the test has masked out a handle bit that would be
required for the test to succeed.
Fix that by extending Q2T_SKIP_HANDLE to incorporate
CTIO_INTERMEDIATE_HANDLE_MARK as well.

Only evaluate the SCSI command type if virt_dev->zero_copy has been

Since inside scst_process_active_cmd() cmd->state can only change after
cmd has been added back to the command list it is safe to perform the
cmd->state check without holding the command list lock. Hence move the
perform the cmd->state check without holding the command list lock.
