This method will search through the database to find a vendor
that matches the MAC address stored in the class using
setMac().
If the $macList parameter is set, the method will use the
array stored in $macList as the data source to find the
MAC vendor instead of the database. The array would have
to be an array with the same characteristics as one
returned from the importVendors()
method when using the $doReturn parameter.
Parameter
string $getDescription - If set
to TRUE, the return value will be an array with keys
'vendor' and 'description'. Normally the method will simply
return the vendor name.
string $macList - An optional
list of MAC-to-vendor relationships to search instead of using
the database.
Return value
mixed - Returns an associative
array if $getDescription is TRUE, returns a
string with the vendor name if $getDescription is FALSE.
If the MAC vendor cannot be found in the vendor list, FALSE is
returned.
