Description (partial)

Symptom:
1. the customer use the LAP2700 with the WiSM2 with 8.0.100.0 version.
2. they observed very slow in getting the DHCP IP address in the AP2700 when compare to the old LAP2600.
3. in the sniffer, we found the AP send out the first DHCP OFFER with the wrong sequence number after the ACTION frame. that's why the client seems ignore this packet and will have to retry after around 8 seconds.
4. for the other client, the problem should be same, but different client might try re-send the DHCP discovery  faster and it might be less noticiable.
5. the problem happened on both AP2700 and AP3700.

Conditions:
