Enhanced DMA RX data path is handled using a single
RX descriptor ring for all VIFs.
Multiple RX status rings are supported, to allow RSS
and multi MSI support.
The driver gets the RX completions via the RX status rings.
The RX status message includes the completed RX buffer ID,
which points to the allocated SKB.
The enhanced DMA RX data flow supports RX chaining, where
multiple SKBs are merged into a single packet.
Enhanced DMA HW supports RX HW reorder offload, enabled by
default and can be disabled via module parameter.

kbuild bot reported a warning but not sure if it's valid, please take a

This is false alarm but looking again on the code I think it is better
to initialize stats.
I'll upload a fix.
