Since this\nkernel is not yet released, if one wishes to test this patch now it\nis suggested to use the aforementioned linux-next tree and modify the\nversion check to align with the version of that tree. Once the kernel\nis released (~December) this will no longer be necessary.\n\n[1] https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=acabf32805f7\n\nCiara Loftus (1):\n net/af_xdp: shared UMEM support\n\n doc/guides/nics/af_xdp.rst | 6 +-\n drivers/net/af_xdp/compat.h | 41 ++++\n drivers/net/af_xdp/meson.build | 4 +\n drivers/net/af_xdp/rte_eth_af_xdp.c | 302 ++++++++++++++++++++++------\n 4 files changed, 289 insertions(+), 64 deletions(-)\n create mode 100644 drivers/net/af_xdp/compat.h" }
