From: Gagandeep Singh <[email protected]> Make burst size checks and MC command fields SoC-aware, enabling bursts larger than 64K on LX2160A with dpni version 8.7+.
The max_burst_size field in dpni_tx_shaping_cfg is widened to uint32_t and the MC command struct is updated to split the value across two 16-bit fields using the new DPNI_BURST_LO/HI macros.
