SUSE-SU-2018:4128-1

This update for openvswitch to version 2.7.6 fixes the following issues:

These security issues were fixed:

• CVE-2018-17205: Prevent OVS crash when reverting old flows in bundle commit (bsc#1104467).
• CVE-2018-17206: Avoid buffer overread in BUNDLE action decoding (bsc#1104467).
• CVE-2018-17204:When decoding a group mod, it validated the group type and command after the whole group mod has been decoded. The OF1.5 decoder, however, tried to use the type and command earlier, when it might still be invalid. This caused an assertion failure (via OVSNOTREACHED) (bsc#1104467).

• ofproto/bond: Fix bond reconfiguration race condition.
• ofproto/bond: Fix bond post recirc rule leak.
