Hello all, I'm using the 2.1.7 version of ixgbe from -CURRENT, backported to FreeBSD 7.1. With some fiddling it seems to work on both 82598 and 82599 controllers.
On 82598, 'ifconfig ix0 -lro' causes dev.ix.0.counters.rxr0.lro_queued and ...lro_flushed to stop incrementing, as expected. There's also a significant throughput hit which would seem to indicate that it took effect. However, it appears that LRO is always enabled on 82599. 'ifconfig ix0 -lro' removes the LRO flag from the port in ifconfig but the ...hw_lro_merge counter continues to increase. The throughput reported by the iperf port is the same with or without LRO on. Any advice? Am I misinterpreting something? Thanks, Andrew P.S. We need to disable LRO because we don't have Appropriate Byte Counting support and LRO causes TCP ACK havoc without it. -------------------------------------------------- Andrew Boyer abo...@averesystems.com _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
