Subject: [PATCH] net-lib.sh:parse_iscsi_root() fix target parsing
18971c
18971c
For targets with colons in the iSCSI target name:
18971c
  "iqn.2000-09.com.foo:storage-system.e2000:00000001cm1p1"
18971c
18971c
the parser was confused with the optional iscsi_iface_name and
18971c
iscsi_netdev_name.
18971c
18971c
This patch reintroduces the old IQN, EUI and NAA parsing and enhances
18971c
the fallback parser by checking the LUN for a numerical value.
18971c
18971c
(cherry picked from commit 36e8ce4fb01824b49697bd0e7ad3ca3c4cfd4297)
