This patch integrates support for shared UMEMs into the AF_XDP PMD.
The feature is currently available in the linux-next tree [1] and
should be available in the v5.10 kernel.

Detailed information on the shared UMEM feature can be found in the
kernel documentation.

Support for the kernel feature is detected in DPDK by querying the
LINUX_KERNEL_VERSION and ensuring a kernel >= 5.10.0. Since this
kernel is not yet released, if one wishes to test this patch now it
is suggested to use the aforementioned linux-next tree and modify the
version check to align with the version of that tree. Once the kernel
is released (~December) this will no longer be necessary.
