Seem to work ok so far. I've made a couple of minor changes (removed some remaining vestiges of the rlb rebalance code, changed the mode of the sysfs hash table files to 0400 after some testing with ping and concurrent "while 1 cat > /dev/null" loops). Unless something awful comes up, I'll post them with my changes later today or tomorrow. -J --- -Jay Vosburgh, IBM Linux Technology Center, fubar@us.ibm.com -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
