LINUX NETMAP DRIVERS

The driver I used for FreeBSD is this one:Ģ) Is the output driver name 'if_ix. The Netmap framework has evolved significantly from its inception as a user-space packet I/O interface to NIC. The initial question is what is 'if_ix.ko' ? Is this intended for FreeBSD and for Linux it should be 'ixgbe.ko'? The readme files points to the same output regardless of Linux/FreeBSD Netmap is available on both Linux and FreeBSD. Intel also describes in the Intel driver for FreeBSD that the same 'ixgbe.ko' should result after compilation. IXGBE is recognized by Netmap also in FreeBSD, but the issue is that the the driver outpout after compilation in FreeBSD is 'if_ix.ko', instead of 'ixgbe.ko' On Linux after compilation the output is 'ixgbe.ko' as a driver. Please read my initial post with more attention. Mainly it is used by Snort and Suricata for IDS/IPS hence I need a proper driver for it

LINUX NETMAP DRIVERS

I talked with the guys on FreeBSD, and they told me Netmap is not supported by ix driver, only by ixgbe driver.ģ) If Netmap works on Linux with the same card and not on FreeBSD, I tend to believe the driver is the issue here.Īll information about NETMAP and accepted drivers are here: sess.total - This is the total of all incoming and outgoing sessions the Connect:Direct server can establish with all remote nodes. On Freebsd using ix driver, Netmap works only in emulation mode, and I achieve only ~150 Mbs/s In the Netmap: Local Node Connection Record - local.node: There are three parameters for controlling the total concurrent sessions with which the Connect:Direct server can establish with all remote nodes. see the top of linux/net/sched/schteql.c for usage and caveats. On Linux using ixgbe driver, Netmap works and I achieve 960 Mbs/s iptables -t nat -A PREROUTING -d 1.2.3.0/24 -j NETMAP -to 5.6.7.0/24 iptables -t nat. Is this a bug?Ģ) Linux, FreeBSD and Netmap supports 'ixgbe' driver, but not IX, what is IX driver? Shouldn't x553 support be included in ixgbe driver as in Linux? The driver for FreeBSD as far as I know is this:ġ) After compilation the following if_if.ko is created as a driver, although in your 'readme files' Intel mentions it should output if_ixgbe.
