-Subject: atl1c: Fix misuse of netdev_alloc_skb in refilling rx ring
-
-From: Neil Horman <nhorman@tuxdriver.com>
-
-commit ebe7fdbaf3e90ea22feade6c9f5e50f42b23b6d8 upstream.
-
-atl1c uses netdev_alloc_skb to refill its rx dma ring, but that call makes no
-guarantees about the suitability of the memory for use in DMA. As a result
-we've gotten reports of atl1c drivers occasionally hanging and needing to be
-reset:
-https://bugzilla.kernel.org/show_bug.cgi?id=54021
-
-Fix this by modifying the call to use the internal version __netdev_alloc_skb,
-where you can set the gfp_mask explicitly to include GFP_DMA.
-
-Tested by two reporters in the above bug, who have the hardware to validate it.
-Both report immediate cessation of the problem with this patch
