REMOVE MAC = 1

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
