Notes on 6708

- There are 2 flavors - 3C and 3CXL.
- 6704 has 16MB per port buffer, 6708 has 200MB per port buffer
- 8 x 10G ports with 40Gbps (2 x 20Gbps) to Fabric (2:1 fabric oversubscription ?)
- 64Gbps local switching (1.25:1 local oversubscription ?)
- 48Mpps switching
- "no hw-module slot x oversubscription" will turn off oversubscription, effectively shutting down port 3,4,7 and 8.
- in non-oversubscribed mode, port 3,4,7 and 8 cannot be unshut and "show interface" output will be "disabled for performance" instead of normal admin disable
- "mac-address-table synchronize" is enabled by default (and fix PFC/DFC MAC synchronization problem )
