From: Jason Xing <kernelxing@xxxxxxxxxxx> Adding more detailed display of softnet_data when cating /proc/net/softnet_stat, which could help users understand more about which can be the bottlneck and then tune. Based on what we've dicussed in the previous mails, we could implement it in different ways, like put those display into separate sysfs file or add some tracepoints. Still I chose to touch the legacy file to print more useful data without changing some old data, say, length of backlog queues and time_squeeze. After this, we wouldn't alter the behavior some user-space tools get used to meanwhile we could show more data.
