We want to create a AXI DMA channel support "lite" that can deal with tuser without requiring the AXI DMA channel mode which requires additional resources and has S2MM limitations for automatic SG table advancement.
The control bus already forwards arbitrary user data from scatter gather entries and vice-versa for status bus. This can be used with a simple state machine to drive/read-in tuser.
