this problem add a new `flags` parameter to ocelot_mact_learn()

Before this patch, there was no way to fill attr.inner_map_fd, necessary
for array_of_maps or hash_of_maps.
This patch adds keyword 'innermap' to pass the innermap, either as an id
or as a pinned map.

$ sudo bpftool map create /sys/fs/bpf/innermap type

spi_setup() already call spi_set_cs() right after calling the
controller setup method, so there is no need for the bitbang driver to
do that. Because of this the chipselect() callback was confusingly
still called when CS is GPIO based.

From: Alban Crequy <al...@kinvolk.io>
bpf_get_current_cgroup_ino() allows BPF trace programs to get the inode
of the cgroup where the current process resides.
My use case is to get statistics about syscalls done by a specific
Kubernetes container. I have a tracepoint on raw_syscalls/sys

bpf_get_current_cgroup_ino() allows BPF trace programs to get the inode

My use case is to get statistics about syscalls done by a specific
Kubernetes container. I have a tracepoint on raw_syscalls/sys_enter and
a BPF map
