Unmap the rx buffer before mapping the new one in rtl8192_rx. Failing to do so quickly exhausts the IOMMU memory during downloads: [...] DMA: Out of SW-IOMMU space for 9100 bytes at device ... Using "iommu=off mem=4g" also fixes the problem because then pci_map_single does not allocate memory. Tested on my personal laptop with a RTL8192E device. Without this patch the kernel quickly runs out of IOMMU memory (downloading 5 MB of data is sufficient to trigger it), with this patch applied I haven't experienced any issues so far.
