Subject: [PATCH net v2 0/2] net: dsa: Fix chip-wide frame size config in some drivers

Some DSA chips support a chip-wide frame size configurations, only. Some
drivers adjust that chip-wide setting for user port changes, overriding 
the frame size requirements on the CPU port that includes tagger overhead.

Fix the mv88e6xxx and b53 drivers and align them to the behavior of other
drivers.

v2: 
  - Skip chip-wide config for non-CPU ports instead of finding the maximim
    MTU over all ports
  - Add a patch fixing the b53 driver as well

v1: https://lore.kernel.org/netdev/20240716120808.396514-1-martin@strongswan.org/

  net: dsa: mv88e6xxx: Limit chip-wide frame size config to CPU ports
  net: dsa: b53: Limit chip-wide jumbo frame config to CPU ports
