Remove the network drivers ice, i40e and iavf if multi-drivers-switch
is set in cmdline, which ensures that ice, i40e and iavf drivers will
not be loaded during initramfs stage.
pxe-network-installer will not be impacted because the parameter
multi-drivers-switch is not set in this stage.
We need do the following steps to switch to the legacy drivers.
1. Add /etc/depmod.d/multi-drivers.conf.
cat /etc/depmod.d/multi-drivers.conf
override ice * extra/ice-1.8.3.1.2
override i40e * extra/i40e-2.18.9
override iavf * extra/iavf-4.4.2
2. depmod
3. Add cmdline parameter multi-drivers-switch=1
4. reboot
Do the following steps to switch back to the latest drivers.
1. Modify /etc/depmod.d/multi-drivers.conf.
cat /etc/depmod.d/multi-drivers.conf
override ice * updates/ice
override i40e * updates/i40e
override iavf * updates/iavf
2. depmod
3. reboot
Testing:
- An ISO image can be built out successfully.
- PXE network install success onto a All-in-One Duplex lab with rt
and std kernel.
- Drivers will not be loaded in initramfs stage.
- Latest driver versions are loaded by default and ddp version correct.
It is 1.3.30.0.
- It can switch to the legacy drivers manually with
/etc/depmod.d/multi-driver.conf and cmdline parameter
multi-drivers-switch=1, ddp version is 1.3.28.0.
