The CONFIG_XEN_FC stuff is used for activating FC(Fibre Channel)
transport layer functionality. I will attach additional patch for the
stuff.


Please note:

The FC transport functionality for PV driver on HVM domain is not
activated even if this stuff is set. It is only available for 2.6.18
kernel for PV domain.
This is why definition of "struct fc_function_template" used for the
FC transport functionality are differrent for each kernel version.
Therefore "#ifdef" switch is needed for each kernel version. We didn't
implement the switch on current implementation.

Best regards,
