    net: use core MTU range checking in core net infra · 91572088

    geneve:
    - Merge __geneve_change_mtu back into geneve_change_mtu, set max_mtu
    - This one isn't quite as straight-forward as others, could use some
      closer inspection and testing
    
    macvlan:
    - set min/max_mtu
    
    tun:
    - set min/max_mtu, remove tun_net_change_mtu
    
    vxlan:
    - Merge __vxlan_change_mtu back into vxlan_change_mtu
    - Set max_mtu to IP_MAX_MTU and retain dynamic MTU range checks in
      change_mtu function
    - This one is also not as straight-forward and could use closer inspection
      and testing from vxlan folks
    
    bridge:
    - set max_mtu of IP_MAX_MTU and retain dynamic MTU range checks in
      change_mtu function
    
    openvswitch:
    - set min/max_mtu, remove internal_dev_change_mtu
    - note: max_mtu wasn't checked previously, it's been set to 65535, which
      is the largest possible size supported
    
    sch_teql:
    - set min/max_mtu (note: max_mtu previously unchecked, used max of 65535)
    
    macsec:
    - min_mtu = 0, max_mtu = 65535
    
    macvlan:
    - min_mtu = 0, max_mtu = 65535
    
    ntb_netdev:
    - min_mtu = 0, max_mtu = 65535
    
    veth:
    - min_mtu = 68, max_mtu = 65535
    
    8021q:
    - min_mtu = 0, max_mtu = 65535
