assuming that you are using a Mellanox CX3 or CX4 PCI boards, you maybe
able to update the code to avoid access to pagemap. pagemap is used to
get and then cache the physaddr. However, since Verbs are used to
register memory by these 2 PMDs, the physical address is not needed.
A dirty hack could be to store any dummy values, and you should be good
almost to go.
best regards,
Vincent
