====================
dwc_eth_qos: stability fixes and support for CMA
This series has bug fixes for the dwc_eth_qos ethernet driver.
Mainly two stability fixes for problems found by Rabin Vincent:
- Successive starts and stops of the interface would trigger a DMA reset timeout.
- A race condition in the TX DMA handling could trigger a netdev watchdog
timeout.
The memory allocation was improved to support use of the CMA as DMA allocator
backend.
