@moogooos I ran into the same problem.. Add a newline to the end of the patch file and run the path -p5 ... line again.

@vdm Thanks for this patch; it works a treat!

Hello,

I went ahead and updated the patch file so that it includes the newline at the end. Hopefully this resolves the error that you were running into.

The new raw file is:

Thanks for this. I prefer to leverage dkms to auto handle rebuilds on kernel updates. Here are the steps I did. Here are some docs from AWS that explain a bit in detail.

wget http://sourceforge.net/projects/e1000/files/ixgbevf%20stable/2.16.1/ixgbevf-2.16.1.tar.gz
tar zxf ixgbevf-2.16.1.tar
mv ixgbevf-2.16.1 /usr/src/
cd /usr/src/ixgbevf-2.16.1
nano dkms.conf #change version - @see http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/enhanced-networking.html#enhanced-networking-ubuntu
curl -L -O https://gist.githubusercontent.com/defila-aws/44946d3a3c0874fe3d17/raw/18e8d8eb53364ab3dea9028c0aa06a3c05dea7b6/patch-ubuntu_14.04.1-ixgbevf-2.16.1-kcompat.h.patch
cd src
patch -p5 < ../patch-ubuntu_14.04.1-ixgbevf-2.16.1-kcompat.h.patch
dkms add -m ixgbevf -v 2.16.1
dkms build -m ixgbevf -v 2.16.1
dkms install -m ixgbevf -v 2.16.1
update-initramfs -c -k all
#stop instance, enable: aws ec2 modify-instance-attribute --instance-id i-xxx --sriov-net-support simple
#create ami then startup instance, verify via:
#aws ec2 describe-image-attribute --image-id ami-xxx --attribute sriovNetSupport
#verify from inside instance via: 
ethtool -i eth0 | grep ixgbevf
#DONE

Thanks!
