OcteonTx3 CN10K silicon supports bigger MTU when compared to 9216 MTU supported by OcteonTx2 silicon variants. Lookback interface supports upto 64K and RPM LMAC interfaces support upto 16K. This patch does the necessary configuration and adds support for PF/VF drivers to retrieve max packet size supported via mbox This patch also configures tx link credit by considering supported fifo size and max packet length for Octeontx3 silicon. This patch also removes platform specific name from the driver name.
