@FieldOrder({"length","writeOffset","readLength","readOffset","supportedProto","cnt","_padMbx"}) public static class Structures.SlaveMailbox extends com.sun.jna.Structure
Slave 邮箱子结构 - 对应 C 端 slave_mailbox_t 原平面字段 mbx_l / mbx_wo / mbx_rl / mbx_ro / mbx_proto / mbx_cnt 收敛为 sub-struct. 嵌入到 EcSlave 中段 (FMMU 函数之后, hasdc 之前), 自然对齐 (无 pack). 64 位下: 5 × short (10) + byte (1) + 1 字节隐式填充 = 12 字节.
