| Provides the basic VCAP functionality for multiple Microchip switchcores |
| |
| A VCAP is essentially a TCAM with rules consisting of |
| |
| - Programmable key fields |
| - Programmable action fields |
| - A counter (which may be only one bit wide) |
| |
| Besides this each VCAP has: |
| |
| - A number of lookups |
| - A keyset configuration per port per lookup |
| |
| The VCAP implementation provides switchcore independent handling of rules |
| and supports: |
| |
| - Creating and deleting rules |
| - Updating and getting rules |
| |
| The platform specific configuration as well as the platform specific model |
| of the VCAP instances are attached to the VCAP API and a client can then |
| access rules via the API in a platform independent way, with the |
| limitations that each VCAP has in terms of its supported keys and actions. |
| |
| Different switchcores will have different VCAP instances with different |
| characteristics. Look in the datasheet for the VCAP specifications for the |
| specific switchcore. |
