    I tried so many things now I didn't even remember doing this but mine is set
    to 40, up from the default of 20.

    Here's the whole config file, some of the values are leftover 'poke and hope'.

    Path: Network/Hardware/Config
    ## Description: Set some general network configuration
    ## Type: string("","-","+")
    ## Default: "+"
    ## ServiceRestart: network
    #
    # DEFAULT_BROADCAST is used when no individual BROADCAST is set. It can get
    one
    # of the following values:
    # "" : don't set a broadcast address
    # "-" : use IPADDR with all host bits deleted
    # "+" : use IPADDR with all host bits set
    DEFAULT_BROADCAST="+"

    ## Type: yesno
    ## Default: yes
    # sometimes we want some script to be executed after an interface has been
    # brought up, or before an interface is taken down.
    # default dir is /etc/sysconfig/network/if-up.d for POST_UP and
    # /etc/sysconfig/network/if-down.d for PRE_DOWN
    GLOBAL_POST_UP_EXEC="yes"
    GLOBAL_PRE_DOWN_EXEC="yes"

    ## Type: yesno
    ## Default: no
    # If ifup should check if an ip address is already in use, set this to yes.
    # Make sure that packet sockets (CONFIG_PACKET) are supported in the kernel,
    # since this feature uses arping, which depends on that.
    # Also be aware that this takes one second per interface; consider that when
    # setting up a lot of interfaces.
    CHECK_DUPLICATE_IP="no"

    ## Type: yesno

    # establishes a connection and is supplied by the peer with a list of
    # nameservers. Or pcmcia needs to set the correct nameserver for the choosen
    # configuration scheme. If you don't like these services to change
    # /etc/resolv.conf at all, then set this variable to "no".
    # If unsure, leave it at the default (which is "yes").

    MODIFY_RESOLV_CONF_DYNAMICALLY="yes"

    ## Type: yesno
