@Josh, @Joseph,
I used this bug to apply the mlx* and ib* changes to the linux-azure
kernels. If AKS really needs another config change for eBPF, please open
a new bug.
Thank you.

Bug description:
eBPF is available as of kernel version 4.15, which is used on AKS nodes.
Enabling JIT eBPF (built-in kernel feature) will speed-up execution of eBPF
aware tools.
eBPF JIT is controlled by the file /proc/sys/net/core/bpf_jit_enable.
More details for eBPF JIT -
https://www.kernel.org/doc/Documentation/sysctl/net.txt
The file /proc/sys/net/core/bpf_jit_enable is not present on AKS nodes.
Also, to support eBPF in AKS, we are requesting to switch the mlx* and
ib* drivers to loadable modules instead of static.
