    "content": "Commit 4c5d9a7fa149 (\"i40e: fix xdp handle calculations\") reintroduced\nthe addition of the umem headroom to the xdp handle in the i40e_zca_free,\ni40e_alloc_buffer_slow_zc and i40e_alloc_buffer_zc functions. However,\nthe headroom is already added to the handle in the function i40_run_xdp_zc.\nThis commit removes the latter addition and fixes the case where the\nheadroom is non-zero.\n\nFixes: 4c5d9a7fa149 (\"i40e: fix xdp handle calculations\")\nSigned-off-by: Ciara Loftus <ciara.loftus@intel.com>\n---\n drivers/net/ethernet/intel/i40e/i40e_xsk.c | 4 ++--\n 1 file changed, 2 insertions(+), 2 deletions(-)",
