atl1: fix 4G memory corruption bug
When using 4+ GB RAM and SWIOTLB is active, the driver corrupts memory by writing an skb after the relevant DMA page has been unmapped. Although this doesn't happen when *not* using bounce buffers, clearing the pointer to the DMA page after unmapping it fixes the problem. http://marc.info/?t=120861317000005&r=2&w=2 Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Jay Cliburn <jacliburn@bellsouth.net> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
