+Furthermore, upon UMEM creation, the kernel allocates a
+physically-contiguous structure, whose size is proportional to the number
+of 4KB pages contained in the UMEM. That allocation might fail when
+the number of buffers allocated by VPP is too high. That number can be
+controlled with the `buffers { buffers-per-numa }` configuration option.
+Finally, note that because of this limitation, this plugin is unlikely
+to be compatible with the use of 1GB hugepages.
