L3XC_PLUGIN_VERSION_MAJOR

#define L3XC_PLUGIN_VERSION_MAJOR   1

A L3 cross connect will send all traffic that is received on the input interface to the [set of] paths requested.

It is a much more memory efficient solution than using a separate IP table for each input interface and much faster than an ABF match all rule.
