/**

 * @brief Linker command/script file
 *
 * This is the linker script for ip_k66f board to allow ethernet
 * interfaces placement.
 */

/*
 * Explicit placement of the ethernet interfaces
 *
 * eth0 is the "master" port for the DSA switch and hence shall be
 * placed on the index (position) 1 (as net_if_get_by_index() uses
 * internally '_net_if_list_start[index - 1]' linker generated symbol).
 *
 * lan{123} shall be placed afterwards (sorted) so the order will be
 * correctly preserved.
 *
 * If ip_k66f have had eth1 interface - it shall be placed afterwards
 *
 * The last entry with `._net_if.static.*` is to accommodate ethernet
 * interfaces created in tests/samples - like e.g. _net_if.static.eth_test)
 * in tests/net/vlan/src/main.c
