vmware的一个bug

fox144215

使用vmware5.5版本（以前都用6.0版本），重新编译内核后死活不能启动，没有找到scsi硬盘，查找相关资料，对fusion模块做如下修改，
系统
正常启动：
static int
GetPortFacts(MPT_ADAPTER *ioc, int portnum, int sleepFlag)
{
    ....................
   /* Now byte swap the necessary fields in the response. */
    pfacts->MsgContext = le32_to_cpu(pfacts->MsgContext);
    pfacts->IOCStatus = le16_to_cpu(pfacts->IOCStatus);
    pfacts->IOCLogInfo = le32_to_cpu(pfacts->IOCLogInfo);
    pfacts->MaxDevices = le16_to_cpu(pfacts->MaxDevices);
    pfacts->PortSCSIID = le16_to_cpu(pfacts->PortSCSIID);
    pfacts->ProtocolFlags = le16_to_cpu(pfacts->ProtocolFlags);
    pfacts->MaxPostedCmdBuffers = le16_to_cpu(pfacts->MaxPostedCmdBuffers);
    pfacts->MaxPersistentIDs = le16_to_cpu(pfacts->MaxPersistentIDs);
    pfacts->MaxLanBuckets = le16_to_cpu(pfacts->MaxLanBuckets);
    /*patch for vmware LSI driver bug, by fox144215*/
    if (!pfacts->MaxDevices)
        pfacts->MaxDevices = 16;
