Simplifying WLAN Section

• Issue AP hopping was needed when PAA and AP (EP)
  are separated
• Before PANA PaC uses AP connected to
  unauthenticated VLAN
• After PANA PaC switches to AP connected to
  authenticated VLAN
• This is because IEEE 802.11i D7.0 does not allow
  any IP traffic to be forwarded on uncontrolled
  port of AP
• IEEE 802.11i D10.0 allows limited IP traffic to
  be forwarded on uncontrolled port of AP
• Resolution
• Text for AP hopping was removed
• A single solution for both co-located and
  separated PAA-EP cases
• Miscellaneous fix Added explicit text that IEEE
  802.11i 4-way handshake is initiated by AP

Simplifying DSL Section

• Issue The following two modes in DSL section are
