Hi All,

In IScsiDxe driver, IScsiPublishIbft ( ) is called from both
IScsiDriverBindingStart and IScsiDriverBindingStop functions. In a
system with more than one network interface and no I_NAME variable, it
is possible that no iBFT tables are installed in start but during exit
boot services, in stop iBFT tables get installed temporarily for
network interfaces other than the first one as driver stop function
gets executed for all network interfaces one at a time.

This happens because the IScsiPublishIbft function removes the iBFT
table and then re-installs it if there are any interfaces detected
leaving out the current one that is being stopped.

How can we improve the decision making logic around the iBFT install
call that works both while starting and stopping the driver but avoids
the temporary installation of ACPI tables ?

Thanx,
