Captive Portal + Voucher not keeping auto-added "Pass-through MAC Auto Entry"
With Captive Portal, the "Enabled Pass-through MAC Auto Entry" should normally keep definitvly the MAC address into table. Regarding documentation there is only one way to delete it: manually.
But in version 2.4.4p3, the auto-added Mac is deleted in same time than Voucher expiration.
Correction find with Forum and Gertjan help.
the captiveportal.inc file , function captiveportal_prune_old_automac() has a block to remove MAC from list.
Keeping log Voucher is expired, remove code about deleting rules and table auto-added line.
