/* Usage:
    BLACK_LIST  = 0
    WHITE_LIST  = 1
    ADD MAC = 0
    REMOVE MAC  = 1

    mac addr will be accepted as a 6 octet mac address with each octet inputted in hex
    for e.g. 00:0a:f5:11:22:33 will be represented as 0x00 0x0a 0xf5 0x11 0x22 0x33
    while using this ioctl

    Syntax:
    iwpriv softap.0 modify_acl
    <6 octet mac addr> <list type> <cmd type>

    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
    eg 2. to delete a mac addr 00:0a:f5:89:89:90 from white list
