From: Tonghao Zhang <redacted> This patch allows user to select queue_mapping, range from A to B. And user can use skbhash, cgroup classid and cpuid to select Tx queues. Then we can load balance packets from A to B queue. The range is an unsigned 16bit value in decimal format. $ tc filter ... action skbedit queue_mapping skbhash A B "skbedit queue_mapping QUEUE_MAPPING" (from "man 8 tc-skbedit") is enhanced with flags: * SKBEDIT_F_TXQ_SKBHASH * SKBEDIT_F_TXQ_CLASSID * SKBEDIT_F_TXQ_CPUID
Once again, you are enforcing policies in kernel, which is not good. Kernel should just set whatever you give to it, not selecting policies like a menu. Any reason why you can't obtain these values in user-space?
