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.

[Kernel-packages] [Bug 1827916] Re: Enable eBPF JIT in the linux-azure kernels
Any updates on that? Besides that eBPF is already enabled, most of the mlx and ib modules are already built as modules, the exceptions are the modules listed on bug #1785822, where it was explicitly requested to built them statically. Is it possible to compile an exact list of the modules that should be changed?
