The changes include: 1. Moves nix_stats_lf_tx/rx structure definition into header file so that it can be reused by the AF driver while fetching representor port stats. 2. Representor PF shares same mbox design as of RVU PF and have same HW resources(TX/RX queues). Hence, mbox and HW resources configuration function APIs are exported so that it can be used by representor driver. 3. Moving the link type checks and tx credit configuration into common API. 4. TX/RX queue memory operations are combined under new API. 5. Add extraction of queue and vlan id to common API so that it can be used while matching mcam traffic rules.
