Interface drivers regularly need to keep track of where each part of a long read buffer should be copied, once that data arrives. Both source and destination are often at an arbitrary bit offset. This queued bit-level copy can help with that, by allowing the driver to perform postponed reads from the receive buffer already when building the transmit buffer, and have those reads executed at a later time when data is available. For simplicity, it uses the linked list implementation list.h imported from the Linux kernel.
