This patch adds support for transferring requests, which are non-contiguous in physical memory, i.e. the data buffer is described by a scatter-list. This allows transferring large requests without relying on error-prone contiguous buffer allocations. This way of allocating requests is already implemented in functionfs and TCM USB functions and automatically used if UDC driver advertises scatter-gather suppport.
