RTL8180 Linux Driver version 1.4  - Support Client mode for either infrastructure or adhoc mode  - Support AP modeRTL8180 Linux Driver version 1.5  - Turn on Dynamic Carrier Sense Function.===============================================================================================< Component >The driver is composed of several parts:    (1)source code         driver module initialization and interface between rtl8180 driver and system call.         r8180_pci_init.c    driver module initialization and register/unregister network device         r8180_pci_init.h    include file         r8180_if.c          interface between rtl8180 driver and system call         r8180_if.h          include file         r8180_type.h        type definition for rtl8180 driver         r8180_export.h      exported function name from rtl8180 driver    (2)object code         rtl8180 driver         priv_part.o         rtl8180 driver object code    (3)Default driver         rtl8180_24x.o       default driver module compiled in kernel 2.4.18.    (4)Makefile         PLEASE SPECIFY INCLUDEPATH CORRECTLY ACCORDING TO YOUR LINUX ENVIRONMENT.         FOR EXAMPLE, " INCLUDEPATH=-I /usr/src/linux-2.4.18-3/include/ " in RedHat7.3.         FOR EXAMPLE, " INCLUDEPATH=-I /usr/src/linux-2.4.18-14/include/ " in RedHat8.0.    (5)wlanup/wlandown         simple script file to activate/shut_down wireless lan.< Installation >Please try to load linux_24x.o first by "insmod -f rtl8180_24x.o".If it doesn't work, you are suggested to compile loadable driver module following the steps as:	(0)Make sure the C-compile version. Run "gcc -v".       If gcc version is 2.xx, use release driver RTL8180_24x_RH73.zip.       If gcc version is 3.xx, use release driver RTL8180_24x_RH90.zip.	(1)Modify macros in Makefile.         KERNELRELEASE - represent kernel release version         IO_FLAGS - pci I/O space mapping         ENDIAN_FLAGS - big/little endian         OP_MODE_FLAGS - Operation on either AP or Client mode         DRV_FLAGS - Driver debugging messge ...etc.    (2)Check pci module initialization and system call interfaces in the provided source code,       r8180_pci_init.c ....etc.	(3)Run 'make' to generate new driver module.        (4)Run 'make install' to install new driver module.	(5)Refer to < Set wireless lan MIBs > and modify script files,              wlanup/wlandown, to set Wireless LAN specific parameters.             Run wlanup/wlandown to activate/shut_down wireless lan.             Usage:               ./wlanup {ap|infra|adhoc}               ./wlandown             Note:               - "./wlanup ap" works if OP_MODE_FLAGS is assigned RTL_ACT_AS_AP in Makefile.               - "./wlanup {infra|adhoc}" works if OP_MODE_FLAGS is assigned RTL_ACT_AS_AP                 in Makefile.< Set wireless lan MIBs >This driver uses Wireless Extension as an interface allowing you to setWireless LAN specific parameters.Current driver supports "iwpriv", manipulate driver private ioctls, to set MIBs.        iwpriv wlan0 wlan_para [parameters]=[val]where        parameter explaination      [parameters]        [val] constraints        -----------------------     -------------       ------------------        Set beacon interval         bcnint              {20~1000} msec        Set channel number          channel             {1~14}        Set basic rates             basicrates          {bit0 = 1Mbps, bit1 = 2Mbps, bit2 = 5.5Mbps, bit3 = 11 Mbps}        Set operational rates       oprates             {bit0 = 1Mbps, bit1 = 2Mbps, bit2 = 5.5Mbps, bit3 = 11 Mbps}        Set authentication type     authtype            {opensystem, sharedkey, both<only AP mode>}        Set desired ssid to scan    ssid2scan           {0~z, less than 32 characters}        Set RTS threshold           rtsthres            {256~2304}        Set fragment threshold      fragthres           {256~2304}        Set preamble mode           preamble            {short,long,auto}        Set network type            networktype         {infra,adhoc,auto}        Set WEP mode                wepmode             {off,wep40,wep104}        Set WEP default key ID      wepdkeyid           {0~3}        Set 1st WEP40 key value     wepkey40_1          {0~f, total 10 characters}        Set 2st WEP40 key value     wepkey40_2          {0~f, total 10 characters}        Set 3st WEP40 key value     wepkey40_3          {0~f, total 10 characters}        Set 4st WEP40 key value     wepkey40_4          {0~f, total 10 characters}        Set 1st WEP104 key value    wepkey104_1         {0~f, total 26 characters}        Set 2st WEP104 key value    wepkey104_2         {0~f, total 26 characters}        Set 3st WEP104 key value    wepkey104_3         {0~f, total 26 characters}        Set 4st WEP104 key value    wepkey104_4         {0~f, total 26 characters}        Set AP ssid                 ssid                {0~z, less than 32 characters}        Set Mac address             macaddr             {0~f, total 6 characters}        Set DTIM period             dtimperiod          {1~255}        Set hidden AP               hiddenAP            {true,false}        Set mac filter policy       addmac              {0~f, total 6 characters}        Delete mac filter policy    delmac              {0~f, total 6 characters}        Set deny mac filter policy  denymacaddr         {0~f, total 6 characters}        Delete deny mac filter      deldenymacaddr      {0~f, total 6 characters}        Set sta expired time        expired_time        {1~100000} *10 msec        Set rate adaptive           autorate            {true,false}        Print help message          helpFor example:        iwpriv wlan0 wlan_para bcnint=100        iwpriv wlan0 wlan_para channel=1        iwpriv wlan0 wlan_para basicrates=0xf        iwpriv wlan0 wlan_para oprates=0xf        iwpriv wlan0 wlan_para authtype=opensystem        iwpriv wlan0 wlan_para ssid2scan=testssid        iwpriv wlan0 wlan_para fragthres=512        iwpriv wlan0 wlan_para preamble=long        iwpriv wlan0 wlan_para wepmode=off        iwpriv wlan0 wlan_para wepdkeyid=0        iwpriv wlan0 wlan_para wepkey40_1=0123456789        iwpriv wlan0 wlan_para wepkey104_1=01234567890123456789012345        iwpriv wlan0 wlan_para networktype=infra        iwpriv wlan0 wlan_para ssid=apssid        iwpriv wlan0 wlan_para macaddr=00e04c8180ff        iwpriv wlan0 wlan_para hiddenAP=true        iwpriv wlan0 wlan_para addmac=00e04c8180ff        iwpriv wlan0 wlan_para denymacaddr=00e04c8180ff        iwpriv wlan0 wlan_para help;Also, you could set parameters as follow:        iwpriv wlan0 wlan_para bcnint=100,channel=1,basicrates=0xf,authtype=opensystem,ssid2scan=testssid< Driver status >The driver status is reported by /proc filesystem.  /proc/rtl8180/status     (link status for client mode)  /proc/rtl8180/ap_status  (link status for ap mode)
