Not really, no, though if you do a lot of data transfer it can actually consume a fair bit of CPU - made better by two somewhat recent patches, commits 01911dab97cb3e21e640aaca82689acec00ed848 and 68972c46f2975d3d61f9dc9f311f77bfc8a8b12b. johannes -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
