Hi,
We are working on open Vswitch 2.4 and the requirement is to add GTP tunnel
headers in flow table so that onos controller can add flows for GTP packets
and the switch captures GTP packets as well. What we have identified so far:
1. Struct sk_buff :-> the structure containing the received packe

Hi Mark,
I thought about how to make this dynamically reconfigurable and I've come
up with a series that generalizes the mechanism used for rx/tx queues
reconfiguration:

I also think that it should be better to introduce 'mtu_request
Thanks for the cleanup, it is really appreciated!
I put my signoff, as you suggested and applied this to master

A netdev provider, especially a PMD provider (like netdev DPDK) might
not be able to change some of its parameters (such as MTU, or number of
queues) without stopping everything and restarting.
This commit introduces a mechanism that allows a netdev provider to
request a restart (netdev_request_re
This fixes multiple error path mistakes in do_add_port, none of which
has been a problem in practice so far. This change will make it easier
for a following commit to return in case of error.
Also, this removes an unneeded special case for tunnel ports.

This just documents what the current code already assumes.

This introduces in dpif-netdev and netdev-dpdk the first use for the
newly introduce reconfigure netdev call.
When a request to change the number of queues comes, netdev-dpdk will
remember this and notify the upper layer via
netdev_request_reconfigure().
The datapath, instead of periodically call
The dpif-netdev datapath keeps ports in a cmap which is written only by
the main thread (holding port_mutex), but which is read concurrently by
many threads (most notably the pmd threads).
When removing ports from the datapath we should postpone the deletion,
otherwise another thread might access
Only the main thread will delete ports after pausing every other
thread. There's no need to keep count.

An upcoming commit will make dpif_poll_threads_set() record the
requested configuration and dpif_run() apply it, so it makes sense to
change the order.

This commit change reconfigure_pmd_threads() to interact with the ports

altered while concurrent readers might access it) and to fail more

Currently we treat set_multiq() calls specially in netdev and dpif-netdev:
every pmd thread must be stopped and set_multiq() is allowed to destroy and
recreate the device.
I think we can improve this by:
* Generalizing the mechanism to allow changing other parameters at runtime
(such as MTU).
