Yes, any NDIS_BUFFER in the chain of buffers can have zero length.
Note that for the receive path, the minimum size of the first
NDIS_BUFFER of an NDIS_PACKET must be at least
OID_GEN_MAXIMUM_LOOKAHEAD or the complete packet, whichever is shorter.
OK, thanks.
No such limitations apply for the transmit path.
