v11->v12
- Fix missing changes old comments pointed out
- Fix new comments for v11
v10->v11
- Fix the left three disputable comments for v9
but not fixed in v10.
v9->v10
- Change struct ovs_key_nsh to
struct ovs_nsh_key_base base;
__be32 context[NSH_MD1_CONTEXT_SIZE];
- Fix new comments for v9
v8->v9
- Fix build error reported by daily intel build
because nsh module isn't selected by openvswitch
v7->v8
- Rework nested value and mask for OVS_KEY_ATTR_NSH
- Change pop_nsh to adapt to nsh kernel module
- Fix many issues per comments from Jiri Benc
v6->v7
- Remove NSH GSO patches in v6 because Jiri Benc
reworked it as another patch series and they have
been merged.
- Change it to adapt to nsh kernel module added by NSH
GSO patch series
v5->v6
- Fix the rest comments for v4.
- Add NSH GSO support for VxLAN-gpe + NSH and
Eth + NSH.
v4->v5
- Fix many comments by Jiri Benc and Eric Garver
for v4.
v3->v4
- Add new NSH match field ttl
- Update NSH header to the latest format
which will be final format and won't change
per its author's confirmation.
- Fix comments for v3.
v2->v3
- Change OVS_KEY_ATTR_NSH to nested key to handle
length-fixed attributes and length-variable
attriubte more flexibly.
- Remove struct ovs_action_push_nsh completely
- Add code to handle nested attribute for SET_MASKED
- Change PUSH_NSH to use the nested OVS_KEY_ATTR_NSH
to transfer NSH header data.
- Fix comments and coding style issues by Jiri and Eric
v1->v2
- Change encap_nsh and decap_nsh to push_nsh and pop_nsh
- Dynamically allocate struct ovs_action_push_nsh for
length-variable metadata.
OVS master and 2.8 branch has merged NSH userspace
patch series, this patch is to enable NSH support
in kernel data path in order that OVS can support
NSH in compat mode by porting this.

Open vSwitch is a multilayer Ethernet switch targeted at virtualized
|
|
environments. In addition to supporting a variety of features
|
|
expected in a traditional hardware switch, it enables fine-grained
|
|
programmatic extension and flow-based control of the network. This
|
|
control is useful in a wide variety of applications but is
|
|
particularly important in multi-server virtualization deployments,
|
|
which are often characterized by highly dynamic endpoints and the
|
|
need to maintain logical abstractions for multiple tenants.
|
|
|
|
The Open vSwitch datapath provides an in-kernel fast path for packet
|
|
forwarding. It is complemented by a userspace daemon, ovs-vswitchd,
|
|
which is able to accept configuration from a variety of sources and
|
|
translate it into packet processing rules.
|
|
|
|
See http://openvswitch.org for more information and userspace
|
|
utilities.
