Thadeu Lima de Souza Cascardo 782428535e qlge: fix size of external list for TX address descriptors ... When transmiting a fragmented skb, qlge fills a descriptor with the fragment addresses, after DMA-mapping them. If there are more than eight fragments, it will use the eighth descriptor as a pointer to an external list. After mapping this external list, called OAL to a structure containing more descriptors, it fills it with the extra fragments. However, considering that systems with pages larger than 8KiB would have less than 8 fragments, which was true before commit a715dea3c8, it defined a macro for the OAL size as 0 in those cases. Now, if a skb with more than 8 fragments (counting skb->data as one fragment), this would start overwriting the list of addresses already mapped and would make the driver fail to properly unmap the right addresses on architectures with pages larger than 8KiB. Besides that, the list of mappings was one size too small, since it must have a mapping for the maxinum number of skb fragments plus one for skb->data and another for the OAL. So, even on architectures with page sizes 4KiB and 8KiB, a skb with the maximum number of fragments would make the driver overwrite its counter for the number of mappings, which, again, would make it fail to unmap the mapped DMA addresses.
