I started off posting a question to freebsd-cloud@ about what would be = necessary to get jumbo frame support on xn0 in a FreeBSD VM running in = AWS EC2. I was advised to post my question to a wider audience (hence = the cross post). Here was my original question: The AWS EC2 Instance Types documentation[1] says that the MTU for the = network interfaces is dependent on the instance type. A post on the AWS = forums[2] by an AWS representative states that the MTU configuration is = available via DHCP. I noticed that all of our T2 instances running FreeBSD have an MTU of = 1500. After searching around a bit, I found this patch[3]. I get the = same results when running the reproduction steps in EC2, despite = ifconfig(8) saying it's using an MTU of 9001. I'm wondering if the patch in 187094 is what's needed to make the xn0 = interface on our FreeBSD instances use jumbo frames? Thanks in advance :) [1] = http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-types.html [2] https://forums.aws.amazon.com/thread.jspa?threadID=3D143674 [3] https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D187094 -- Bradley T.
