[-- Attachment #1 --] Hi, I have netmap working with the T6 cards now. However, performance is very poor. It seems to take several milliseconds after a NIOCTXSYNC ioctl before the tail is updated? In case it matters, here is what is in loader.conf: hw.cxgbe.num_vis=2 hw.cxgbe.fl_pktshift=0 hw.cxgbe.ntxq=1 hw.cxgbe.nrxq=1 hw.cxgbe.qsize_txq=512 hw.cxgbe.qsize_rxq=512 hw.cxgbe.cong_drop=1 hw.cxgbe.pause_settings=1 hw.cxgbe.autoneg=0 hw.cxgbe.nm_rx_nframes=1 hw.cxgbe.nm_rx_ndesc=1 Lars [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEmpq0ZpSoejRmyhheVLXDCb9wwVcFAltGGw8ACgkQVLXDCb9w wVfO4w/9GtwBdc3B45ShRyecErfzWyYsMc+Y6ESsSMAN5PRVaPzW1nKru8CFkDIx z1uxBTbQoktxkoMSBpqKLCZu2Pdz7D80qPg3WLl9F1q1mFKOUS6JdaeTirGdOfKG 5tP2/rMfb+ac9McbK8qmXM7xgG2pH4hoiEpRldaronz8XZH3FirNKtL1ayxtlga4 67WS7BQ8o2PglcN8QMVziG7k0hlcFXFxMrsVEDhkV/tu9SUR60el0zNc2vlH6MwI UvOtDnJywMDfyKX4+ejz05JHnpbAX9Wrw0iDDd/aiMSDnMFVtkdSP4FzTy5K4aW6 Mqj4WA35+HM4b2wZyz08mThFlzM7kvnj42EPhra2SCEl7a/SO0O45Nsj9VJQtTpL dPxXHMjZAeHAz2vBbuR6kHrpplpQKvgWc4lPqGL7+/Dv/8wYi8XSvkvsVv8qWfPN J/2iC3qZwRyrgcj46qsnnqALRs/bR7HTqaPvVzLo8KoN+t2g9mAk8ngSfOKA8Lvi sXT06OQj98yErWo5uRMevcX9ZJHnob4iVoTiBUvIRVUXTwNYBKgWGnzYhpTSFaUt EmSW1MIeVG+yCe8N8hc+z1kx5UWuFzx97Q4HqDvHb9n1IYGDkI70Jb7VKqvnR7xn d20EO8LKS9A1f43DOzC/V9mAiVEQ7A2y+qdpgZUBOlsUAYLt9fQ= =rwOB -----END PGP SIGNATURE-----
