nlmsg error Cannot allocate memory

["Mathew, Elza" <elza.mathew@xxxxxxxxx>]

Hi,
I am trying to run the XDP sample programs (located at samples/bpf/xdp1 and samples/bpf/xdp2) on the ixgbe driver. I am getting this error:

./xdp1 15
nlmsg error Cannot allocate memory
link set xdp fd failed

Kernel version : 4.13.0+
Driver version : 5.1.0-k

Is there any setup issues I might be doing wrong? I have BPF_SYSCALL=y enabled in my kernel config file.
Thanks!
Elza
