netdev-afxdp: NUMA-aware memory allocation for XSK related memory.
Currently, the AF_XDP socket (XSK) related memory are allocated by main
thread in the main thread's NUMA domain. With the patch that detects
netdev-linux's NUMA node id, the PMD thread of AF_XDP port will be run on
the AF_XDP netdev's NUMA domain. If the net device's NUMA domain
is different from the main thread's NUMA domain, we will have two
cross-NUMA memory accesses (netdev <-> memory, memory <-> CPU).
This patch addresses the aforementioned issue by allocating
the memory in the net device's NUMA domain.
