Add some very crude hacks which allow the iscsi-target to work with IPv6: Mar 5 23:43:45 sys3 iscsi-target: > Discovery login from iqn.1994-04.org.NetBSD.iscsi-initiator:agc on 7f00:1::1002:cbc Mar 5 23:43:45 sys3 iscsi-target: < Discovery logout from iqn.1994-04.org.NetBSD.iscsi-initiator:agc on 7f00:1::1002:cbc Mar 5 23:43:45 sys3 iscsi-target: > Normal login from iqn.1994-04.org.NetBSD.iscsi-initiator:agc on 7f00:1::1002:cbc Mar 5 23:43:48 sys3 iscsi-target: < Normal logout from iqn.1994-04.org.NetBSD.iscsi-initiator:agc on 7f00:1::1002:cbc These have still to be cleaned up, but this will happen over the next few days. Update the TODO list to reflect the current state.
