[Bug 1574955] [NEW] iSCSI sanboot failed with multiple NICs

[Rui Mao]

Public bug reported:

My computer has multiple Intel NICs, but only 1 connected. I configured
this one to boot from iSCSI. I could install Ubuntu 14.04 on the iSCSI
disk successfully. But after the reboot, the process stopped after
getting IP address of all NICs.

The attachment is the screenshot.

I check the /run folder, there was no net-*.conf indeed. But if I run
the 'ipconfig eth0' manually, the /run/net-eth0.conf appeared. And I
could run /scripts/local-top/iscsi and continue the boot process.

I did another try after connecting all NICs, and the process passed with
few retry of getting IP.

So I think the getting IP process has a bug, it cannot get IP of
multiple NICs concurrently if any of them cannot get IP via DHCP or have
no link.
