[Click] live reconfiguration (repost...)

[Eddie Kohler]

Hi Tom,

The right approach depends on how much the config needs to change.  If 
you're just changing a queue length, for example, a write handler 
should be sufficient.  The manual pages document most handlers.  For 
example, if your queue is named "q":

    % echo 500 > /click/q/capacity

If you're making a bigger change, use the "click-install -h" option to 
"hotswap" the config.  Much of the state from the old config will get 
swapped into the new.  For example, if both configs have a queue named 
"q", then all of the old "q"'s packets will be inserted into the new 
"q".
