Subject: [PATCH 4/7] Install the driver of physical device for a SR-IOV
|
|
virtual device
|
|
|
|
Currently, network dumping failed over a NIC that is a Single Root I/O
|
|
Virtualization (SR-IOV) virtual device. Usually the driver of the
|
|
virtual device won't specify the dependency on the driver of the
|
|
physical device. So to fix this issue, the driver of the physical device
|
|
needs to be found and installed as well.
|
|
|
|
Fixes: a65dde2d ("Reduce kdump memory consumption by only installing needed NIC drivers")
