xsk: expose xdp_umem_get_{data,dma} to drivers
Move the xdp_umem_get_{data,dma} functions to include/net/xdp_sock.h, so that the upcoming zero-copy implementation in the Ethernet drivers can utilize them. Also, supply some dummy function implementations for CONFIG_XDP_SOCKETS=n configs. Signed-off-by: Björn Töpel <bjorn.topel@intel.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org>
