Remove 'ixgb' from HEAD

2017-12-28 Thread Kevin Bowling
The ixgb driver was used only briefly by one sub family of devices in the first half of the 2000s. It's not a power efficient card with a massive on board xenpak. The driver saw little specific (not API/treewide stuff) maintenance post FreeBSD 5 in which the last real intentional commit directly

Julian, That looks exactly like what I want! It also looks like what I thought I was doing. I have no idea why it worked for you and not for me. :-( I will copy and paste tonight after work (making changes for em0 and em1 on my own test system) and see if I can get it to work. If it works, I

The netgraph bridge would probably forward the 802.1x frames, but the man page says that firewalling on the netgraph bridge is not supported. I need to process with the firewall all of the other traffic that is not EAPOL frames. John L. Lyon PGP Key Available At

Linux netmap memory allocation

2017-12-28 Thread Charlie Smurthwaite
Hi, I'm just starting to use netmap and it is my intention to do zero-copy forwarding of frames between a large number of NICs. I am using Intel i350 (igb) on Linux. I therefore require a large memory area for rings and buffers. My calculation: 32 NICs * 2 rings (TX+RX) * 256 frames * 2048 bytes

Hi, To answer my own question, I have resolved this, there were seemingly 3 errors in my use of the API: 1) I did not initialize the req struct. Some uninitialized data were being passed to the ioctl. I feel silly. 2) Values greater then 1 do not seem to be accepted by nr_arg2, setting this to 1

It works!!! In virtual machine land at least, it works! It will be interesting to see what happens when the rubber meets the road and I actually test it "in the field." The issue was a missing single line that was not obvious from the man pages: sudo ngctl connect eapfilter: ix1: eapout low
