A learner table is typically used for learning or connection tracking,
where it allows for the implementation of the "add on miss" scenario:
whenever the lookup key is not found in the table (lookup miss), the
data plane can decide to add this key to the table with a given action
with no control plane intervention. Likewise, the table keys expire
based on a configurable timeout and are automatically deleted from the
table with no control plane intervention.

A selector table is made up of groups of weighted members, with a
given member potentially part of several groups. The select operation
returns a member ID by first selecting a group based on an input group
ID and then selecting a member within that group based on hashing one
or several input header/meta-data fields. It is very useful for
implementing an ECMP/WCMP-enabled FIB or a load balancer. It is part
of the action selector described by the P4 Portable Switch
Architecture (PSA) specification.

There is no reason for the DPDK libraries to all have 'librte_' prefix on
the directory names. This prefix makes the directory names longer and also
makes it awkward to add features referring to individual libraries in the
build - should the lib names be specified with or without the prefix.
Therefore, we can just remove the library prefix and use the library's
unique name as the directory name, i.e. 'eal' rather than 'librte_eal'
