This commit implements LACP, a protocol which allows directly
connected switches to automatically negotiate which links may
participate in bonds. This commit disables LACP by default. Once
sufficiently tested, LACP will be enabled in "active" mode on
bonded ports, and "passive" mode on all others.
Bug #4213.
Provides ability to match over IPv6 traffic in the same manner as IPv4.
Currently, the matching fields include:
- IPv6 source and destination addresses (ipv6_src and ipv6_dst)
- Traffic Class (nw_tos)
- Next Header (nw_proto)
- ICMPv6 Type and Code (icmp_type and icmp_code)
- TCP and UDP Ports over IPv6 (tp_src and tp_dst)
When defining IPv6 rules, the Nicira Extensible Match (NXM) extension to
OVS must be used.

Datapath IDs are unsigned, but dpid_from_string() was parsing them as
signed integers, which caused high values to be capped at INT64_MAX.
Also, document that datapath IDs may not be all-zero.

The length of a datapath was changed from 48 bits to 64 bits in OpenFlow
0.9. For parity, we increased the management id size to match.
NOTE: This is the final commit in the OpenFlow 0.9 set. Starting with
this commit, OVS is OpenFlow 0.9-compliant.
The bonding code in vswitch sends out gratuitous learning packets that
are supposed to teach switches but not cause anything else to happen on
the network. Some upcoming code wants to synthesize packets with similar
properties, so factor this code into a new function so that it can be
used in both places.
