we use KSDK2.0 with K64 and LWIP.
In file "ethernetif.c" the address of the external Ethernet Phy is hardcoded to 0 in serveral functions.
We use the switching Phy KSZ8863MLL. To get access to the complete Phy information I have to use "phyAddr" = 1 and "phyAddr" = 2.
--> The address of external Phy should be managed globally for the whole Ethernet IF.
