It's unnecessary and heavy. To improve it, add two debugfs directories "tx_bd_info" and "rx_bd_info", and create a file for each queue under these two directories, and query the bd info of specific queue by "cat tx_bd_info/tx_bd_queue*" or "cat rx_bd_info/rx_bd_queue*", return the result to userspace, rather than record in dmesg. The display style is below: $ cat rx_bd_info/rx_bd_queue0 Queue 0 rx bd info: BD_IDX L234_INFO PKT_LEN SIZE... 0 0x0 60 60... 1 0x0 1512 1512... $ cat tx_bd_info/tx_bd_queue0 Queue 0 tx bd info: BD_IDX ADDRESS VLAN_TAG SIZE... 0 0x0 0 0... 1 0x0 0 0...
