This patch adds support for using FCoE during the installation. This patch
merely lays the initial ground work, there is more work todo:
- The system will not boot without manual help after the install, as
dracut / mkinitrd do not support FCoE yet
- If FCoE is not used for / but for example for /srv, then information
about the nic used for FCoE needs to be written in a to be defined
config file in the system, and rc.sysinit needs to be thought to read
this file and bring up FCoE SAN's / Fabrics not used for /
- kickstart support for FCoE still needs to be done
