Title:
Include nfp driver in linux-modules
Status in linux package in Ubuntu:
Confirmed
Bug description:
SRU Justification:
------------------
[Impact]
* Currently the driver for Netronome Agilio SmartNICs, nfp.ko, is included
in linux-moudles-extra.
An implication of this is that on minimal installs, where the
linux-modules but not linux-modules-extra
packages are available, the nfp.ko module cannot be installed. In
particular this means the driver for
any VFs of Netronome Agilio SmartNICs which have been made available to
guests using PCI pass-through
cannot be used by those guests if they have installed using Canonical
cloud images, a likely scenario.
In contrast the driver for the i40e is provided in the linux-modules
package and thus guests can
access their VFs in the scenario described above.
Thus we do not believe it is unreasonable to request that nfp.ko be
included in linux-modules rather
than linux-modules-extras. And we believe that this warrants SRU inclusion
as it is the difference between
users-of guests being able to use Netronome Agilio SmartNICs and not be
able to use them.
This is a packaging update request and included no request to change the
kernel source code,
thus no backports are requred.
[Test Case]
* Install system using Canonical cloud images
* Observer that
/lib/modules/*/kernel/drivers/net/ethernet/netronome/nfp/nfp.ko is
missing;
* If an Netronome Agilio SmartNIC device is present, via PCI pass-through or
otherwise,
that the nfp driver is not loaded and no netdevs are present for the
Netronome Agilio SmartNIC.
[Regression Potential]
* Any bugs present in the nfp.ko will now be exposted to guests. However as
the same nfp.ko driver binary
is already included in and available on installs that have access to
linux-modules-extra, this does not
seem an unreasonable burden.
[Other Info]
* None
