> When we have a context descriptor on Tx of a packet from the vector
> paths, that means that we always have 32-bytes being written per
> descriptor/per packet, so the stores are always 32-bit aligned. This
> means we can use aligned stores for each single descriptor store, and
> that we never need to do an initial descriptor write for alignment when
> doing a burst of descriptors.
