How to modify packet content at list of NET_BUFFER structures at N

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?

Hi Every guru:
It seems that nobody answers my question. Is it very difficult to handle or
grasp?
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!

Thanks in advance!!
