File 0310-95iscsi-set-rd.iscsi.firmware-for-qla4xxx-sessions.patch of Package dracut.4406

Subject: 95iscsi: set 'rd.iscsi.firmware' for qla4xxx sessions

The qla4xxx driver can run with or without open-iscsi support,
depending on the setting of the 'ql4xdisablesysfsboot' module
parameter.
When the parameter is set to '0', dracut needs to call
'iscsiadm -m fw' to trigger iSCSI login, so we need to set
the 'rd.iscsi.firmware' dracut variable. But this will then
fail if the parameter is set to '1', as in these cases the
list of firmware targets is empty.
To cover both scenarios this patch reshuffles 'handle_firmware'
in iscsiroot.sh to continue if iscsiadm -m fw fails but iscsi
sessions are present.
