Separate $port['ifDescr'] and $port['ifName'] filtering in is_port_valid()

Hello,

Currently, the configuration variable "bad_if" and "bad_if_regexp" are used to filtered port on $port['ifDescr'] and $port['ifName'] in includes/entities/port.inc.php.

   // FIXME. Prefer regexp

  if ($valid_ifDescr && str_icontains_array($port['ifDescr'], (array)$config['bad_if'])) {

    $bi = $GLOBALS['str_last_needle'];

    print_debug("ignored (by ifDescr): ".$port['ifDescr']." [ $bi ]");

    return FALSE;

  }

  if ($valid_ifName && $nosame_ifName && str_icontains_array($port['ifName'], (array)$config['bad_if'])) {

    $bi = $GLOBALS['str_last_needle'];

    print_debug("ignored (by ifName): ".$port['ifName']." [ $bi ]");

    return FALSE;

  }

I have problems with this in a Juniper and Nokia environment.
The two manufacturers do not use the field in the same way, Nokia add ifAlias in the ifDescr :

$config['bad_if'] = array("em", "me", "dsc", "tap", "gre", "gr", "pe", "mt", "ipip", "pime", "pimd", "mtun", "demux", "ip", "pe", "vt", "mt", "pd", "cbp", "pp", "lt", "ut", "ud", "lc", "lsi", "pfe", "pfh", "esi", "jsrv");

NOKIA :

Xignored (by ifDescr): lag-10, IP interface, IPYX/012345/800/ABC customer name [ ip ]

  [1342177290] => array(
                    [ifDescr]      => string(101) "lag-10, IP interface, IPYX/012345/800/ABC customer name via esat-1/1/1, esat-1/1/2 and esat-1/1/3"
                    [ifAlias]      => string(82) "IPYX/012345/800/ABC customer via esat-1/1/1, esat-1/1/2 and esat-1/1/3"
                    [ifName]       => string(6) "lag-10"
                    [ifType]       => string(13) "ieee8023adLag"
                    [ifOperStatus] => string(2) "up"
                  )

JUNIPER :

  [576] => array(
             [ifDescr]      => string(12) "ge-1/1/4.100"
             [ifAlias]      => string(36) "IPYX/12345/001/ABC customer name."
             [ifName]       => string(12) "ge-1/1/4.100"
             [ifType]       => string(6) "l2vlan"
             [ifOperStatus] => string(14) "lowerLayerDown"
           )

Maybe interesting to have possibility to split  $port['ifDescr'] and $port['ifName'].
Or define "bad_if" and "bad_if_regexp" by OS?
In the meantime, I search with "bad_if_regexp" instead "bad_if", or $config['os'][$os]['ports_ignore']. But less easy.

Thank you!
