From cd782656da9037150502a16bbbc46272e00f9b1b Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Thu, 8 Jun 2017 18:34:13 -0400 Subject: [PATCH] net: dsa: mv88e6xxx: rework jumbo size operation Marvell chips have a Jumbo Mode to set the maximum frame size (MTU). The mv88e6xxx_ops structure is meant to contain generic functionalities, no driver logic. Change port_jumbo_config to port_set_jumbo_size setting the mode from a given maximum size value. There is no functional changes since we still use 10240 bytes. At the same time, correctly clear all Jumbo Mode bits before writing.
