The PPv2.2 IP has a different TX and RX descriptor layout compared to PPv2.1. In order to prepare for the introduction of PPv2.2 support in mvpp2, this commit adds accessors for the different fields of the TX and RX descriptors, and changes the code to use them. For now, the mvpp2_port argument passed to the accessors is not used, but it will be used in follow-up to update the descriptor according to the version of the IP being used. Apart from the mechanical changes to use the newly introduced accessors, a few other changes, needed to use the accessors, are made: - The mvpp2_txq_inc_put() function now takes a mvpp2_port as first argument, as it is needed to use the accessors. - Similarly, the mvpp2_bm_cookie_build() gains a mvpp2_port first argument, for the same reason. - In mvpp2_rx_error(), instead of accessing the RX descriptor in each case of the switch, we introduce a local variable to store the packet size. - In mvpp2_tx_frag_process() and mvpp2_tx() instead of accessing the packet size from the TX descriptor, we use the actual value available in the function, which is used to set the TX descriptor packet size a few lines before.
