i40e-dkms is not used after kernel update

Related bug:

Problem:
After installing new kernel your system started to use stock driver, that is shipped with kernel. Compare before:

modinfo i40e
filename: /lib/modules/3.13.0-92-generic/updates/dkms/i40e.ko
version: 1.3.47

apt-get update && apt-get dist-upgrade

and after kernel update:
modinfo i40e
filename: /lib/modules/3.13.0-95-generic/kernel/drivers/net/ethernet/intel/i40e/i40e.ko
version: 0.3.36-k

That file comes from this package: linux-image-extra-3.13.0-95-generic

Looks like custom package with latest dkms driver was built due to instability of stock driver:

Ask:
add
AUTOINSTALL=yes
to
/usr/src/i40e-1.3.47/dkms.conf

and then install new kernel as usual. Kernel installation will trigger rebuilding of i40e dkms module, and you will not have to run dpkg-reconfigure

My full bash session showing that AUTOINSTALL=yes helps:

Alexander, is this bug about MOS 9.1?

[Alexander Bozhenko (alexbozhenko)]

Sorry forgot to specify. No, it is about 9.0.

[Alexander Bozhenko (alexbozhenko)]

I didn't check in 9.1 though

Actually the dkms.conf is luck of the AUTOINSTALL=yes parameter on the master and 9.x branch
