    mac addr will be accepted as a 6 octet mac address with each octet inputted in hex

    while using this ioctl

    Syntax:
    iwpriv softap.0 modify_acl

    Examples:
    eg 1. to add a mac addr 00:0a:f5:89:89:90 to the black list
    iwpriv softap.0 modify_acl 0x00 0x0a 0xf5 0x89 0x89 0x90 0 0
