+ driver.delete_id=
+ [PCI]
+ Specified pci device format(s) will mask built-in
+ driver id tables, preventing devices from
+ automicatically attaching to built-in or module
+ drivers. Later attachment should be done by adding the
+ deleted id back through the "new_id" sysfs interface.
+ Format: <vendor>:<device>[:<subvendor>:<subdevice>]\
+ [:class][:class_mask][, ...]
+ PCI_ANY_ID masks should use the full 32-bit format.
+ Examples: virtio-pci.delete_id=ffffffff:ffffffff
+ nvme.delete_id=1234:5678,1111:ffffffff
+
dhash_entries= [KNL]
