Accept a new variable `$IFB_PATTERN` which is used as a printf(1) pattern to generate the IFB interface name from the primary interface name. The default is `ifb4%s` which corresponds to the pre-existing behavior. Signed-off-by: Ivan Shapovalov <[email protected]>

Out of curiosity, what is the motivation for this? |
Some less-than-configurable monitoring software that uses hardcoded patterns of ignored interface names. There is a pattern for ifb interfaces, but it does not match |
|
Fair, may I ask to maybe add this to the commit description (maybe even reveal that monitoring software's name)? So far the fixed naming for sqm created IFBs has helped in the past to detect cases where users accidentally tried multiple traffic shaping solutions in parallel... |

Yes, please document the reason for the change in the commit message :) |
