agc 32306cea7e I have a nasty feeling it's time to sell all my guitars:
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.
