smbios_probe that will be called by smbios_detect as well as

Fix UEFI PXE boot on a NIC that isn't the first NIC.
In UEFI it appears all available NICS are present to pass network traffic.
This gives the capability to load the loader.efi from disk then set
currdev="net3:" and then all I/O will over over the 2nd NIC. On this
machine is appears the first handle is the first NIC in IPv4 mode and
then the 2nd handle is the first NIC in IPv6 mode. The 3rd handle is
the 2nd NIC in IPv4 mode. The fix is to index into the handle based

in the range.

- Add bit definitions for the various Activiate Microcode actions.
- Add the Sequential Access Logical Block Protection support bit,

As of SPC-4, a single report of "REPORTED LUNS DATA HAS CHANGED"
is to be given per I_T nexus. Once it is reported, the unit
attention condition should be cleared for all LUNS attached to
an I_T nexus.
Previously that only happened when a REPORT LUNS command was
processed.
This behavior may be different (according to SAM-5) when the
UA_INTLCK_CTRL bits are non-zero in the control mode page but
CTL does not currently support that.
So, in view of the spec, whenever we report a LUN inventory
change unit attention, clear it on all LUNs for that
particular I_T nexus.
Add a new function, ctl_clear_ua() that will clear a unit
attention on all LUNs for the given I_T nexus.
One field in the extended inquiry data that we could potentially
report at some point is the maximum supported sense data length.
To do that, we would the SIM to report (via path inquiry
perhaps) how much sense data it is able to send.

Extended Inquiry VPD page.
