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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
