The iSCSI behaviour is undesirable, but the whole writing of NM_CONTROLLED=no for iSCSI will go away as soon as NetworkManager is fixed to not down devices when it takes over control, which should be fixed soon.If that's fixed soon, shouldn't we not need the hack for FCoE either?
No, because as I've explained before (and I really wish people would start understanding this) FcOE is not a network based storage protocol. FcOE does raw, direct encapsulation of FC frames (which is a storage protocol like sata) in ethernet frames (The MTU even changes to 2300 to make things fit), so in essence the NIC becomes a storage controller. So NetworkManager should not try to touch the NIC in any way and this is not a hack. FCoE basically is: use the NIC as an FC storage controller as its cheaper then a real one. Regards, Hans
