Please accept our apologies for the inconvenience. There are a lot of bugs to go through, and a lot of them have become stale. As a result, we’re conducting a mass bug update across all Fedora 20 kernel bugs.

The bottom-half feature net rx action is used to process incoming frames. Its execution is triggered whenever a driver informs the kernel that input frames are present. The flow of control through the feature is depicted in Figure 10-5.
Net rx action’s task is straightforward: it scans the poll list list of devices with something in their ingress queue and calls the corresponding poll virtual feature for each one until one of the following conditions is met:
The size of the queue is limited by the value of neTDev max backlog, as we saw in the section “Managing Queues and Scheduling the Bottom Half.” This value is used to calculate net rx action’s budget. However, since net rx action uses interrupts, new frames can be added to a device’s input queue while it is running. As a result, the number of available frames which surpass the budget, and net rx action must take action to ensure that it does not run too long.
The system is relocated to the end of poll list if dev->poll returns because the device quota was not high enough to dequeue all the buffers in the ingress queue (in which case the return value is nonzero).

As a result of the server’s numerous docker containers and networks, it has multiple Linux bridges and veth interfaces. However, the concern is with the physical interface. There aren’t any VLANs set up.
Since data copying via TCP (rsync) operates at 1G line speed, only a small number of TCP packets can be harmed. (I expect TCP drops to have a significant impact on transmission efficiency due to the smaller window size.)
The netif receive skb() kernel function locates a packet’s corresponding CPU and queues packets in that CPU’s queue. Packets will be dropped if the queue for that processor is complete and already at maximum size. Determine if the backlog needs to be increased before fine-tuning this environment. When the netdev backlog queue overflows, a counter in the second column of the /proc/net/softnet stat file is incremented. Netdev max backlog should be increased if this value is increasing over time.
It may be appropriate to extend the time that SoftIRQs are permitted to run on the CPU on occasion. The netdev budget is the term for this. The budget’s default value is 300. If the third column in /proc/net/softnet stat is increasing, this value can be doubled, implying that the SoftIRQ did not receive enough Processor time.
