With the new EDMA descriptor format, a single descriptor can contain up

let the hardware add the padding internally instead of using memmove on

Felix,
This patch again introduced "ath: Failed to stop TX DMA!" for AR9380+ chips.
After reverting this, the errors are completely gone away. Please look into this ASAP.
How frequent are these errors in your tests? I ran several tests on
embedded hardware with AR9380 and didn't notice any issues.
