Hi,

Please note that this is expected to conflict with net-next commit:
99be56171fa9 net/mlx5e: SHAMPO, Re-enable HW-GRO.

Resolution is

         u8         reserved_at_400[0x1];
         u8         min_mkey_log_entity_size_fixed_buffer_valid[0x1];
         u8         reserved_at_402[0x1e];

         u8         reserved_at_420[0x20];

         u8         reserved_at_440[0x8];
         u8         max_num_eqs_24b[0x18];
         u8         reserved_at_460[0x3a0];

Thanks,
Tariq
