I see. Since eepro100 just uses a fixed set of RX buffers in the ring (ie. the DMA links are never changed) it works.
This adapter was definitely developed for a system that has to have PCI device DMA and CPU cached data accesses in the same coherency space in order to use their weird RX chaining thing.
So essentially, e100 needs to have it's RX logic rewritten so that it uses a static RX descriptor set of buffers and skb_copy()'s them to push the packets into the stack. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
