Net policy needs to know device information. Currently, it's enough to
only get irq information of rx and tx queues.
This patch introduces ndo ops to do so, not ethtool ops.
Because there are already several ways to get irq information in
userspace. It's not necessory to extend t

This patch tries to initialize NET policy for all the devices in the
system. However, not all device drivers have NET policy support. For
those drivers who does not have NET policy support, the node will not be
showed in /proc/net/netpolicy/.

Current implementation forces CPU and queue 1:1 mapping. This patch
introduces the function netpolicy_update_sys_map to create this mapping.
The result is stored in netpolicy_sys_info.
If the CPU count and queue count are different, the remaining
CPUs/queues are not used for now.

It is a big challenge to get good network performance. First, the network
performance is not good with default system settings. Second, it is too
difficult to do automatic tuning for all possible workloads, since workloads
have different requirements. Some workloads may want high
When ieee_setpfc() gets called, PAUSE frames are not necessarily
disabled on the port.
Check if PAUSE frames are disabled or enabled and configure the port's

The socket/task can only be benefited when it register itself with

When the device tries to transmit a packet, netdev_pick_tx is called to
find the available Tx queues. If the net policy is applied, it picks up
the assigned Tx queue from net policy subsystem, and redirect the
traffic to the assigned queue.

User can write policy name to /proc/net/netpolicy/$DEV/policy to enable
net policy for specific device.
When the policy is enabled, the subsystem automatically disables IRQ

accordingly.

Since we may not get all the information required for rule until the
