Martin Willi 967879893c net: dsa: b53: Limit chip-wide jumbo frame config to CPU ports ... [ Upstream commit c5118072e2 ] Broadcom switches supported by the b53 driver use a chip-wide jumbo frame configuration. In the commit referenced with the Fixes tag, the setting is applied just for the last port changing its MTU. While configuring CPU ports accounts for tagger overhead, user ports do not. When setting the MTU for a user port, the chip-wide setting is reduced to not include the tagger overhead, resulting in an potentially insufficient chip-wide maximum frame size for the CPU port. As, by design, the CPU port MTU is adjusted for any user port change, apply the chip-wide setting only for CPU ports. This aligns the driver to the behavior of other switch drivers.
