Netmap from mac8/3/2023 ![]() If it can't be done by an automated process, then it requires, make config scripts, or tinkering with the driver code itself?īut I can tell you that you are wasting your time there within the netmap source code tree. That's where the changes have to be made to convert over to said in Porting BGE Driver to said in Porting BGE Driver to IFLIB.: The problems you are experiencing with slow speeds are within the NIC drivers themselves and their corresponding C source code. But I can tell you that you are wasting your time there within the netmap source code tree. Specifically it is complaining about the syntax, but I suspect the compiler is getting confused by some missing macro definitions or else missing include files. The particular error you are hitting during the compilation of pkt-gen is likely due to a problem with include files and macro definitions in your FreeBSD environment. It bridges a traffic stream between two interfaces, or an interface and the host stack, using netmap. If you want a sample app that more closely mimics the inline mode of the IDS/IPS packages, you want to use the bridge sample application found in the same directory tree as pkt-gen. This is not a trivial task, and is certainly not something an automated process is likely to accomplish for any driver. To actually convert a driver to use iflib, you will need to locate the driver's C source code in the FreeBSD source tree and make required changes there to replace certain routines with their iflib equivalents. The interface parameter you provide on the command line is just to tell the utility which interface to send the packet stream out on. It just generates a packet stream for transmission using netmap. The pkt-gen program is just a demonstation utility (or think sample application) provided for netmap developers to test with. There is no "conversion of a driver to iflib" possible by simply compiling and running pkt-gen. The instructions you are following make no sense. I tried will lower case "i" also.ĭo you know what's said in Porting BGE Driver to said in Porting BGE Driver to IFLIB.: I reached steps 6 and I have an issue, the commad pkt-gen -I ix0 -f rx or pkt-gen -I ixgbe0 -f rx will just print a list of pkt-gen commands. Hello I tried to use your tutorial, for ixgbe driver. Run Gmake, which converts the driver and launch cc to compile it: $ gmake.Run pkt-gen on NIC driver, example, in my case it is the Broadcom driver bge: #pkt-gen -I bge0 -f rx.Go to the Netmap tool: $ cd /netmap/apps/pkt-gen.Install these packages: Git, Gmake, and Gcc or Clang…note, if you install FreeBSD with SCR Tree, all those would already installed.Install FreeBSD (11 or 12) on a virtual machine.Also, please note that I did not need to do this as I took another option as stated here: said in Porting BGE Driver to IFLIB.: Please note in the above step 7, you will be copying the file from your FreeBSD VM, so you may need a jump drive to transport. Your NIC driver would now be supported by Netmap so you can use Suricata and soon Snort in inline mode. copy the file and place in your pfSense production box: /usr/local/bin - $ sudo cp pkt-gen /usr/local/bin Run Gmake, which converts the driver and launch cc to compile it: $ gmakeħ. Run pkt-gen on NIC driver, example, in my case it is the Broadcom driver bge: #pkt-gen -I bge0 -f rxĦ. Go to the Netmap tool: $ cd /netmap/apps/pkt-genĥ. Install these packages: Git, Gmake, and Gcc or Clang…note, if you install FreeBSD with SCR Tree, all those would already installed.Ĥ. Install FreeBSD (11 or 12) on a virtual machine.Ģ. That’s when the Netmap developer pointed out that he had provided tools to enable any driver to port to the IFLib, which supports Netmap…see man page: The first suggestion was for me to look at how the vmx(4) was ported to the IFLib: That quickly became extremely overwhelming to say the least. Just another update to this thread to share what I had learned. So, I have access to the BGE source code.how to start? I spoke here of a plan here:() however, I am sure others could use the BGE driver as well. Also, the BGE driver 1000mb is not in version 12. FreeBSD is removing or has removed several old drivers (10/100mb) or limited used drivers from version 12. ![]() ![]() Of course that immediately appeared overwhelming. That led me to look at how the VMware driver was ported here: So, I contacted both the Netmap creator as well as the BGE driver creator (he hasn't looked at it for over 15yrs) and shared my intention. ![]() I have been wanting to use Suricata, and soon Snort inline mode with Netmap but the BGE driver isn't supported. I am also a longtime Mac person who likes to re-purpose Mac hardware. I have very limited knowledge on software development and is more of an end user as well as an open source enthusiast. I am embarking on a project into a dark place without a flashlight.porting the BGE driver to the IFlib. ![]()
