Consider using "context" or "ctx" instead. I might help avoid being mistaken as a DMA hardware feature.

No strong opinion, though. Whatever fits nicely in the documentation is a good choice.

A small anecdote: We once had to name an important parameter in our product, and it came down to the choice of two perfectly good names. We chose the shortest name, only because it fit better into the GUI.

One more thing:

The DPDK project is aiming to use inclusive code language. (Ref: https://www.dpdk.org/blog/2020/07/22/dpdk-governing-board-update-july-2020/)

Please replace the word "slave" with something politically correct.
