Transmit descriptor\ncounts are not modified because they don't need to change due to the\nspeed of the interface, or for power managed CPUs, but the code is\nsimplified to a fixed value for the transmit default.\n\nSigned-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com>\n---\n drivers/net/ethernet/intel/ice/ice.h | 19 ++-----------------\n 1 file changed, 2 insertions(+), 17 deletions(-)", "diff": "diff --git a/drivers/net/ethernet/intel/ice/ice.h b/drivers/net/ethernet/intel/ice/ice.h\nindex cd30fc87d7ea..36de705397f9 100644\n--- a/drivers/net/ethernet/intel/ice/ice.h\n+++ b/drivers/net/ethernet/intel/ice/ice.h\n@@ -47,23 +47,8 @@ extern const char ice_drv_ver[];\n #define ICE_MIN_NUM_DESC\t64\n #define ICE_MAX_NUM_DESC\t8160\n #define ICE_DFLT_MIN_RX_DESC\t512\n-/* if the default number of Rx descriptors between ICE_MAX_NUM_DESC and the\n- * number of descriptors to fill up an entire page is greater than or equal to\n- * ICE_DFLT_MIN_RX_DESC set it based on page size, otherwise set it to\n- * ICE_DFLT_MIN_RX_DESC\n- */\n-#define ICE_DFLT_NUM_RX_DESC \\\n-\tmin_t(u16, ICE_MAX_NUM_DESC, \\\n-\t max_t(u16, ALIGN(PAGE_SIZE / sizeof(union ice_32byte_rx_desc), \\\n-\t\t\t ICE_REQ_DESC_MULTIPLE), \\\n-\t\t ICE_DFLT_MIN_RX_DESC))\n-/* set default number of Tx descriptors to the minimum between ICE_MAX_NUM_DESC\n- * and the number of descriptors to fill up an entire page\n- */\n-#define ICE_DFLT_NUM_TX_DESC\tmin_t(u16, ICE_MAX_NUM_DESC, \\\n-\t\t\t\t ALIGN(PAGE_SIZE / \\\n-\t\t\t\t\t sizeof(struct ice_tx_desc), \\\n-\t\t\t\t\t ICE_REQ_DESC_MULTIPLE))\n+#define ICE_DFLT_NUM_TX_DESC\t256\n+#define ICE_DFLT_NUM_RX_DESC\t2048\n \n #define ICE_DFLT_TRAFFIC_CLASS\tBIT(0)\n #define ICE_INT_NAME_STR_LEN\t(IFNAMSIZ + 16)\n", "prefixes": [ "S28", "8/9" ] }
