The tunables are useful for setting defaults for all interfaces. :( I use hw.igb.rx_processing_limit=-1 in loader.conf at work so that we can ensure that all igb interfaces in a given system have that setting. This is more scalable than having to set the right number of entries in /etc/sysctl.conf.local on different machines, etc, without spamming the console during boot with warnings about tweaking non-existing sysctls, etc. Please consider keeping the tunables where the tunables are used to set default settings for all adapters from the loader but per-device sysctls are used post-boot to provide runtime, per-device settings. -- John Baldwin _______________________________________________ svn-src-all@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
