"pcnetGetMac" error in source code

I found a bug on the input parameter for a function in source code(maybe a "clerical error"),Although the function hasn't been used as yet , I think it will cause the problem if it is used. here are the information for the bug:

function name:pcnetGetMac,

file:/src/vbox/devices/network/devpcnet.cpp static DECLCALLBACK(int) pcnetGetMac(PPDMINETWORKCONFIG pInterface, PPDMMAC *pMac) {

PCNetState *pData = INETWORKCONFIG_2_DATA(pInterface); memcpy(pMac, pData->aPROM, sizeof(*pMac)); return VINF_SUCCESS;


file:/include/vbox/pdmifs.h typedef PDMMAC *PPDMMAC; DECLR3CALLBACKMEMBER(int, pfnGetMac,(PPDMINETWORKCONFIG pInterface, PPDMMAC *pMac));

the purpose on function is to output MAC address(6 Bytes), but pay attention to the second input parameter, the type is "PPDMMAC *" (double pointer), after execute "memcpy(pMac, pData->aPROM, sizeof(*pMac))", obviously it can't get result that we want.

so,it should change the type for input parameter from "PPDMMAC *" to "PPDMMAC".
