[PATCH net-next 2/5] net: lan966x: Rename lan966x_fdma_get_max_mtu

From: Horatiu Vultur
Date: Wed Oct 19 2022 - 10:07:27 EST


Rename the function lan966x_fdma_get_max_mtu to lan966x_get_max_mtu
because it doesn't have anything to do with fdma. Because of this
rename, the function is moved also in a different file.
