平台：

Wifi模块：雷凌RT2070(芯片其实和3070一样，只是去掉了802.11n的功能)

Linux内核：Linux 2.6.27

UI:Android 1.5

MCU:NXP LPC3250

问题：

从官网上下载最新的Ralink3070的驱动，编译后，加载rt3070sta.k正常，ifconfig ra0 up时出现

错误。

原因:

3070的驱动中HTTX_BUFFER.field.WirelessPacket[MAX_TXBULK_SIZE],MAX_TXBULK_SIZE过大

[include/chip/mac_usb.h:169]

view plaincopy to clipboardprint?
  1. typedef struct __HTTX_BUFFER{   
  2.     union{   
  3.         UCHAR           WirelessPacket[MAX_TXBULK_SIZE];   
  4.         HEADER_802_11   NullFrame;   
  5.         PSPOLL_FRAME    PsPollPacket;   
  6.         RTS_FRAME       RTSFrame;   
  7.     }field;   
  8.     UCHAR           Aggregation[4];  //Buffer for save Aggregation size.   
  9. } HTTX_BUFFER, *PHTTX_BUFFER;  
typedef struct __HTTX_BUFFER{ union{ UCHAR WirelessPacket[MAX_TXBULK_SIZE]; HEADER_802_11 NullFrame; PSPOLL_FRAME PsPollPacket; RTS_FRAME RTSFrame; }field; UCHAR Aggregation[4]; //Buffer for save Aggregation size. } HTTX_BUFFER, *PHTTX_BUFFER;

MAX_TXBULK_SIZE定义在include/iface/rtmp_usb.h

view plaincopy to clipboardprint?
  1. #define MAX_TXBULK_SIZE         (LOCAL_TXBUF_SIZE*BULKAGGRE_SIZE)  
#define MAX_TXBULK_SIZE (LOCAL_TXBUF_SIZE*BULKAGGRE_SIZE)

LOCAL_TXBUF_SIZE=2048, 只需把BULKAGGRE_SIZE从默认的100改为60就好了。

BULKAGGRE_SIZE定义在include/os/rt_linux.h中

类似的错误信息，其他的原因：
