90 prepare it for being transmitted on the wire.
91 The driver may opt to copy those resources to a DMA buffer or it may bind them.
97 As it processes each frame in the chain, if the device driver has
102 flags, it must check whether either apply for the given frame using the

133 If the message block was copied to a DMA buffer, then it is allowed to call

139 Times when this happens may include the device driver being in a state where it
144 The device driver should not free the chain when it does not have enough

162 Note that because it is the device driver that is calling this function to
163 indicate resources are available, it is very important that it only return
