Subject: [PATCH] gianfar: synchronize DMA API usage by free_skb_rx_queue w/
gfar_new_page

From: Arseny Solokha <redacted>

In spite of switching to paged allocation of Rx buffers, the driver still
called dma_unmap_single() in the Rx queues tear-down path.

Except for the dma-debug part generating the warning, the implementation of 
dma_unmap_single() looks identical to dma_unmap_page(), both wrappers calling 
ops->unmap_page() with same params.
But for consistency, dma_unmap_page() seems the better choice indeed.
Thanks.
