How to modify packet content at list of NET_BUFFER structures at N
in [Device Drivers]

From: George Lee on 17 Nov 2009 03:28 Hi: NDIS 6 takes fully new data structure NET_BUFFER/NET_BUFFER_LIST, therefore how to modify packet included at above structures? My guess is as follows: a. Create new MDL chain list ->b. replace existing MDL list with newly-created one By doing so, it is no need to allocate NET_BUFFER or NET_BUFFER_LIST unlike previous NDIS 5.x scheme. Is that right? Can someone or guru lighten me with hint on how to modify packet content at list of NET_BUFFER structures at NDIS 6 along send and receive path? -- George Lee VoIP anti-blocking guru www.speed-voip.com

I know there is few advisiable documents on how to manipulate packet at NET_BUFFER structure. Welcome Microsoft NDIS expert to join it and help me greatly!
