Hi Narasimham!
I've tried to reproduce the issue with the two most recent kernels available
for ubuntu 1704, and it seems fixed.
I didn't spend time looking for which patch fixed it. I guess it was fixed at
Linux 4.10.0-15-generic, newest 4.10.0-19-generic also works fine.
Shallow explanation for this issue is: when unbinding /binding the
device driver the kernel wasn't generating the events udev has to
capture to take a corresponding action, thus the network configuration
wasn't happening.
Now it's easy to see many events during {un,/}bind:
1 - Started udev's monitor:
root@redhot:~# udevadm monitor --tag-match="enP1p12s0f0" &
[1] 5226
2 - Unbinded the device
root@redhot:~# echo 0001:0c:00.0 > /sys/bus/pci/drivers/tg3/unbind

Hi,
To bind a device to a driver, the device must first not be controlled by any
other driver. Can you check for 'driver' in the below before you bind ?
$ tree /sys//bus/pci/devices/001c:60:00.0
Thank you.
== Comment - Murilo Fossa Vicentini
Just adding some information, this is not a driver specific issue, this was
also seen with tg3 and i40e adapters . This behavior is a regression when
compared to Ubuntu 16.04 where the interfaces where properly reconfigured upon
bind with the information set in /etc/network/interfaces
