There is no such module. If it was upstreamable, Intel would have obtained
it a long ago

When is this the case? With a 4096 byte page, a couple 1518 byte Ethernet
packets can fit. A 9038 byte Jumbo wont fit.
Or is it to ease
I hoped such a kernel module would already exist, but I am surprised
that DPDK would not rely on it. Maybe there is a limitation I cannot
see. I'll keep searching. Francois, maybe you know the answer?

Hi,
My hope was that packet segments would all be smaller than one page
(either normal pages or huge pages) to guarantee physical memory
continuity which is needed by some drivers (read non vfio drivers for
PCI).
Francois Ozog's experience (with dpdk)shows that this hope will fail
in some case: n
