Hi. I read most of the netmap paper. In short, cool work :) I have one question... is this meant only for use with dedicated tap interfaces? Or will it be integrated with the mangement interface?
Example... Today: fxp0 - onboard NIC, 192.168.0.10, ssh, httpd, smtp, tcpdump, etc. ixgbe0 - PCIe addon NIC, tap interface, netmap Tomorrow: ixgbe0 - all the above functions in one NIC It would seem to me that an 'emulate an interface' shim/driver could be written that would hook into netmap below and provide all the normal interface semantics above. netmap interface <--> emulation driver <--> 'net0' interface So example... /etc/rc.conf:netmap_emulate1='ixgbe0 net0' /etc/rc.conf:netmap_emulate2='em0 net1' /etc/rc.conf:netmap_emulate3='fxp1 net2' /etc/rc.conf:ifconfig_net0='inet 10.0.0.3/24' ifconfig net0 192.168.0.10/24 -alias ifconfig net0 ::1 tcpdump, httpd, sshd, ... ipfw, pf, netgraph, vlan, bridge, carp, ... and all the other various capabilities of a physical NIC, etc... Also, though perhaps not needed for line rate capture, but for making a standard interface to them... will various 10/100/1000 NICS such as fxp, em, de, bfe, etc... end up being netmap capable? _______________________________________________ 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"
