The problem with this\nis we only write tail on 8 descriptor boundaries, but next_to_use is\nupdated whenever we clean Rx descriptors. Fix this by comparing the\nvalue we are about to write to tail with the previously written tail\nvalue. This will prevent duplicate Rx tail bumps.\n\nSigned-off-by: Brett Creeley <brett.creeley@intel.com>\n---\n drivers/net/ethernet/intel/ice/ice_txrx_lib.c | 2 +-\n 1 file changed, 1 insertion(+), 1 deletion(-)", "diff": "diff --git a/drivers/net/ethernet/intel/ice/ice_txrx_lib.c b/drivers/net/ethernet/intel/ice/ice_txrx_lib.c\nindex 35bbc4ff603c..6da048a6ca7c 100644\n--- a/drivers/net/ethernet/intel/ice/ice_txrx_lib.c\n+++ b/drivers/net/ethernet/intel/ice/ice_txrx_lib.c\n@@ -10,7 +10,7 @@\n */\n void ice_release_rx_desc(struct ice_ring *rx_ring, u32 val)\n {\n-\tu16 prev_ntu = rx_ring->next_to_use;\n+\tu16 prev_ntu = rx_ring->next_to_use & ~0x7;\n \n \trx_ring->next_to_use = val;\n \n", "prefixes": [ "S37", "v3", "04/15" ] }
