This patch tries to utilize tuntap rx batching by peeking the tx
virtqueue during transmission, if there's more available buffers in
the virtqueue, set MSG_MORE flag for a hint for backend (e.g tuntap)
to batch the packets.

Hi:
This series tries to implement tx batching support for vhost. This was
done by using MSG_MORE as a hint for under layer socket. The backend
(e.g tap) can then batch the packets temporarily in a list and
submit it all once the number of bacthed exceeds a limitation.
Tests shows obvious improve
We can only process 1 packet at one time during sendmsg(). This often
lead bad cache utilization under heavy load. So this patch tries to do
some batching during rx before submitting them to host network
stack. This is done through accepting MSG_MORE as a hint from
sendmsg() caller, if it was set,
This patch tries to do several tweaks on vhost_vq_avail_empty() for a
better performance:
- check cached avail index first which could avoid userspace memory access.
- using unlikely() for the failure of userspace access
- check vq->last_avail_idx instead of cached avail index as the last
step.

In a few cases the err-variable is not set to a negative error code if a
function call in typhoon_init_one() fails and thus 0 is returned
instead.
It may be better to set err to the appropriate negative error
code before returning.

The IRQ is disabled by writing to the completion ring doorbell. This
should be done before the hardware completion ring is freed for correctness.
The current code disables IRQs after all the completion rings are freed.
Fix it by calling bnxt_disable_int_sync() before freeing the completion
rings.
The existing hardware RFS mode uses one hardware RSS context block
per ring just to calculate the RSS hash. This is very wasteful and
prevents VF functions from using it. The new hardware mode shares
the same hardware RSS context for RSS placement and RFS steering.
This allows VFs to enable RFS.

mlx4_QP_FLOW_STEERING_DETACH_wrapper first removes the steering
rule (which results in freeing the rule structure), and then
references a field in this struct (the qp number) when releasing the

Since this memory was freed, it could reallocated

Single send WQE in RX buffer should be stamped with software

Oftenly, introducing side effects on packet processing on the other half
of the stack by adjusting one of TX/RX via sysctl is not desirable.
There are cases of demand for asymmetric, orthogonal configurability.
This holds true especially for nodes where RPS for RFS usage on top is
configured and t

When we send a packet for our own local address on a non-loopback

commit 0b922b7a829c ("net: original ingress device index in PKTINFO"), the
original ingress device index would be set as the loopback interface.
