net: dsa: b53: Use dev_err_probe()

2024-08-21T01:22:44Z

Rather than print an error even when we get -EPROBE_DEFER, use dev_err_probe() to filter out those messages.

net: dsa: b53: Limit chip-wide jumbo frame config to CPU ports

2024-07-18T11:09:12Z

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.

And make sure this is done for the MLO_AN_PHY case, where it actually makes sense, contrary to b53_adjust_link() which only did it for fixed-PHY configurations where it does not make sense.

Call b53_adjust_531x5_rgmii() and b53_adjust_5325_mii() from b53_phylink_mac_config() when we have a fixed PHY in preparation for removing b53_adjust_link(). Also move b53_adjust_63xx_rgmii() to b53_phylink_mac_config() where it logically belongs.
