Please upgrade I40E driver

[chandramouli Chekuri]

Detailed bug description:
 1. the memory leak problem is fixed when kernel was upgraded to 4.4.0-128-generic (the leak problem affects kernel 4.4.0-116)

2. However, fuel installs network interface driver i40e-dkms. This driver breaks the LACP bonding: not all slave interfaces are discovered by the bond, interface speed is not recognized.

3. when the fuel-installed i40-dkms driver is removed and the nodes uses the 1.4.25-k i40e driver (that comes natively with the kernel), LACP bonding works fine.

The winning combination, therefore, seems to be the 4.4.0-128-generic kernel with the 1.4.25-k i40e network interface driver.

Steps to reproduce:
 See Detailed Description
Expected results:
 LACP would work fine
Actual result:
 This driver breaks the LACP bonding: not all slave interfaces are discovered by the bond, interface speed is not recognized
Reproducibility:
 See Description
Workaround:
 Let kernel use the default driver version and disable i40-dkms driver.
Impact:
 LACP is not working, not all slave interfaces are discovered by the bond, interface speed is not recognized.
Description of the environment:
 Operation system: Ubuntu
 Versions of components: MOS9.2
 Network model: Neutorn + OVS

We wait for confirmation from fields that 2.4.6 is working as expected. Until this I'm moving it to Incomplete.

Moving to 9.2-mu-8 since there are no evidence that the issue is in the driver and not in NICs themselves. Also I'm decreasing the importance.
