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 Signed-off-by: Neil Horman <nhorman@tuxdriver.com> CC: Jay Cliburn <jcliburn@gmail.com> CC: "David S.
