At the core of this patch set is removing the assumption in Open vSwitch

The implementation relies on the presence of pop_eth and push_eth actions
in datapath flows to facilitate adding and removing Ethernet headers as
appropriate. The construction o
Extend the ovs flow netlink protocol to support L3 packets. Packets without

OVS_KEY_ATTR_ETHERTYPE attribute is mandatory.
Push/pop vlan actions are only supported for Ethernet packets.

It's not allowed to push Ethernet header in front of another Ethernet

preserves the invariant that L3 packet never has a vlan tag.

Use a hole in the structure. We support only Ethernet so far and will add
a support for L2-less packets shortly. We could use a bool to indicate
whether the Ethernet header is present or not but the approach with the
mac_proto field is more generic and occupies the same number of bytes in the
struc
On tx, use hard_header_len while deciding whether to refragment or drop the
packet. That way, all combinations are calculated correctly:
* L2 packet going to L2 interface (the L2 header len is subtracted),
* L2 packet going to L3 interface (the L2 header is included in the packet
lenght),
* L3 p
We'll need it to alter packets sent to ARPHRD_NONE interfaces.
Change do_output() to use the actual L2 header size of the packet when
deciding on the minimum cutlen. The assumption here is that what matters is
not the output interface hard_header_len but rather the L2 header of the

Support receiving, extracting flow key and sending of L3 packets (packets
without an Ethernet header).
Note that even after this patch, non-Ethernet interfaces are still not
allowed to be added to bridges. Similarly, netlink interface for sending and

We have a st
Type of debugfs_real_fops() is longer than parameters and
the name, so there is no way to break the declaration nicely.
We have to go over 80 characters.

This patch updates the driver code so that we do bulk updates of the page
reference count instead of just incrementing it by one reference at a time.
The advantage to doing this is that we cut down on atomic operations and
this in turn should give us a slight improvement in cycles per packet. In

The ARM architecture provides a mechanism for deferring cache line
invalidation in the case of map/unmap. This patch makes use of this
mechanism to avoid unnecessary synchronization.
A secondary effect of this change is that the portion of the page that has
been synchronized for use by the CPU sh
This change allows us to pass DMA_ATTR_SKIP_CPU_SYNC which allows us to
avoid invoking cache line invalidation if the driver will just handle it
via a sync_for_cpu or sync_for_device call.

This patch adds a function that allows us to batch free a page that has

drop a page being used in the page frag alloc cache. With this drivers can

Add support for mapping and unmapping a page with attributes. The primary
use for this is currently to allow for us to pass the
