eql_enslave enslaves a PPP or SLIP network interface to another, named master
interface or eql device.
The MTU must match the MTU of your serial line device, otherwise, eql_enslave
just fails when it is called. You have also to turn off Van-Jacobson
compression on your slave devices.
Once the eql device is configured, it will stay up and running until
you shut it down manually or reboot. If you have the eql support compiled as
a module then all you have to do is to remove the module after downing the
interface.
Note that you have to connect to a terminal server capable of doing load
balancing or another Linux box to use EQL.
