This patch tries to support ND versus ARP for OVN.
It adds a new OVN action 'na' in ovn-controller side, and modify lflows
for 'na' action and relevant packets in ovn-northd.
First, for ovn-northd, it will generate lflows per each lport with its
IPv6 addresses and mac addresss, with 'na' action, such as:
match=(icmp6 && icmp6.type == 135 &&
(nd.target == fd81:ce49:a948:0:f816:3eff:fe46:8a42 ||
nd.target == fd81:ce49:b123:0:f816:3eff:fe46:8a42)),
action=(na { eth.src = fa:16:3e:46:8a:42; nd.tll = fa:16:3e:46:8a:42;
outport = inport;
inport = ""; /* Allow sending out inport. */ output; };)
and new lflows will be set in tabel ls_in_arp_nd_rsp, which is renamed
from previous ls_in_arp_rsp.
Later, for ovn-controller, when it received a ND packet, it frames a
template NA packet for reply. The NA packet will be initialized based on
ND packet, such as NA packet will use:
- ND packet eth.src as eth.dst,
- ND packet eth.dst as eth.src,
- ND packet ip6.src as ip6.dst,
- ND packet nd.target as ip6.src,
- ND packet eth.dst as nd.tll.
Finally, nested actions in 'na' action will update necessary fileds
for NA packet, such as:
- eth.src, nd.tll
- inport, outport
Since patch port for IPv6 router interface is not ready yet, this
patch will only try to deal with ND from VM. This patch will set
RSO flags to 011 for NA packets.
This patch also modified current ACL lflows for ND, not to do conntrack
on ND and NA packets in following tables:
- S_SWITCH_IN_PRE_ACL
- S_SWITCH_OUT_PRE_ACL
- S_SWITCH_IN_ACL
- S_SWITCH_OUT_ACL

A few minor changes related to logical switch commands:
- Use "ls" instead of "lswitch" to be more consistent with other
command changes.
- Use commands where possible in ovn unit tests.
- Update references from "lswitch" to "ls" (code) or "switch" (user).

Highlighted requirement on how a fresh sandbox is expected
before doing each of the tutorial sections.
Also added some mentioning of the gdb flags available for
debugging ovn programs.

All of these links when viewing OVN-Tutorial on github, but most of
these links didn't work when viewing OVN-Tutorial.md.html in dist-docs.
Use full github links so that they always work (as long as you have
internet access).

Add a section that gives a quick introduction to applying ACLs. It
discusses how the ACLs are translated into OVN logical flows. It doesn't
get down to the OpenFlow level because that's not supported in
ovs-sandbox yet. Instead, it provides a reference to an OpenStack
related blog post that talks about how OVN ACLs are used there and gives
examples of the resulting OpenFlow flows.
In theory, once we have a userspace conntrack implementation available,
we'll be able to provide better suppot for it in ovs-sandbox.

Add links to several man pages. Also fix a minor typo.
Note that openvswitch.org needs to be updated as it's missing the
ovn-northd man page.

While working on OVN and OVN integration, I've collected a set of
scripts for quickly setting up simple test environments using
ovs-sandbox with OVN enabled. It seemed like they could be useful to
others for learning about OVN or doing quick testing.
This patch introduces an ovs-sandbox based tutorial for exploring OVN
features in a simulated environment.
