/* Since devlink regions have a fixed size and the static config has a variable
 * size, we need to calculate the maximum possible static config size by
 * creating a dummy config with all table entries populated to the max, and get
 * its packed length. This is done dynamically as opposed to simply hardcoding
 * a number, since currently not all static config tables are implemented, so
 * we are avoiding a possible code desynchronization.
