* the time of one poll and might resolve automagically before the next
* poller run happens. Without this special case this would lead to new
* ports added to the database each time this situation occurs. To give
* the user the choice between »a lot of new ports« and »some poll runs
* are missed but ports stay stable« the 'ignore_unmapable_port' option
* has been added to configure this behaviour. To skip the port in this
* loop is sufficient as the next loop is looping only over ports found
* in the database and "maps back". As we did not add a new port to the
* DB here, there's no port to be mapped to.
*
* I'm using the in_array() check here, as I'm not sure if an "ifIndex"
* can be legally set to 0, which would yield True when checking if the
