Symptom:
On nexus 7000 series switches, modifying IPv6 ACLS which can result in disruptive ipv6 update after the system has been upgraded non-disruptively from a version prior to 6.2(6) with IPv6 ACLS present, including for control-plane policing, may cause a linecard reset on F2/F2E modules due to aclqos service crash.

Upgrade from any version < 626 to 626 or Later.
Once the new version is up, any change in IPv6 Policies that ca trigger a disruptive IPV6 update can result in aclqos crash due to incorrect compression ID.
