Description (partial)

Release-note

Symptom:
The VLAN encapsulation is supported using a mix of hash and overflow TCAM.  In certain cases, such as trying to configure sequential double tag with very small variation of 1st tag and sequential 2nd tag, it can cause excessive collision and thus unable to meeting 64K/NP.  However, 64K/NP can be achieved via configuring scaled single tag configuration on the same NP and/or adjust the sequential double tag pattern.

Conditions:
Perform scaled configuration beyond 50K/NP
