My plan is to yank out a TX ring and to use it solely with netmap to receive packets but want to make sure the kernel won't be receiving any packets on this ring. Based on a quick search this is something that ethtool would be able to do on Linux but I doubt this can be done on FreeBSD using the same tool? Thanks for your help, David
