/**

*
* 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
