For setting rx queues, this patch add rules for Flow Director filters.
Since we may not get all the information required for rule until the
first package arrived, it will add the rule after recvmsg. The first
several packages may not use the assigned queue.

Usually, application as a whole has specific requirement. Applying the
net policy to all sockets one by one in the application is too complex.
This patch introduces per task net policy to address this case.
Once the per task net policy is applied, all the sockets in the

Some drivers like i40e driver does not support separate tx and rx queues
as channels. Using rx queue to stand for the channels, if queue_pair is
set by driver.

Current implementation searches the hash table to get assigned object
for each transmit/receive packet. It's not necessory, because the
assigned object usually remain unchanged.
This patch store the assigned queue into netpolicy_reg struct. So it

Setting net policy for all tx and rx queues according to policy name.
For i40e driver, the policy only changes per queue interrupt moderation.
It uses new ethtool callback (per queue coalesce setting) to configure
the driver.

MIX policy is combine of other policies. It allows different queue has
different policy. If MIX policy is applied,
/proc/net/netpolicy/$DEV/policy shows per queue policy.
Usually, the workloads requires either high throughput or low latency.
So for current implementation, MIX poli

Hi,
Here's some of my thoughts on how a connector format for the DT could
be done. Sorry it's taken longer than I hoped - I've been pretty
swamped in my day job.
This is pretty early thoughts, but gives an outline of the approach I
prefer.
So.. start with an example of a board DT including a wi

The ttm_tt_destroy() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.
