Qdisc being serviced often as well. If net_ rx _action() hogs the cpu, net_tx_action() is delayed and NIC can stall. I wrote this patch because I was investigating a regression when a Google application began using BQL enabled kernels. About the latency in itself, following commit is way more interesting. commit c10d73671ad30f5 (softirq: reduce …
net_ rx _action() can mask irqs a single time to transfert sd->poll_list into a private list, for a very short duration. Then, napi_complete() can avoid masking irqs again, and net_ rx _action() only needs to mask irq again in slow path. This patch removes 2 couples of irq mask/unmask per typical NAPI run, more if multiple napi were triggered.

It’s not a regression, it’s an old problem. And the rule is: machines that _used_ to work are more important.
