Additional functionality is needed to support ++BSS-transition mobility. The additional required functionality ++is provided by the reassociation service. Reassociation is a DSS. ++The reassociation service is invoked to 'move' a current association ++from one AP to another. This keeps the DS informed of the current ++mapping between AP and STA as the station moves from BSS to BSS within ++an ESS. Reassociation also enables changing association attributes ++of an established association while the STA remains associated with ++the same AP. Reassociation is always initiated by the mobile STA. ++ ++5.4.3.1 Authentication ++... ++A STA may be authenticated with many other STAs at any given instant. ++ ++5.4.3.1.1 Preauthentication ++ ++Because the authentication process could be time-consuming (depending ++on the authentication protocol in use), the authentication service can ++be invoked independently of the association service. Preauthentication ++is typically done by a STA while it is already associated with an AP ++(with which it previously authenticated). IEEE 802.11 does not require ++that STAs preauthenticate with APs. However, authentication is required ++before an association can be established. If the authentication is left ++until reassociation time, this may impact the speed with which a STA can ++reassociate between APs, limiting BSS-transition mobility performance. ++The use of preauthentication takes the authentication service overhead ++out of the time-critical reassociation process. ++ ++5.7.3 Reassociation ++ ++For a STA to reassociate, the reassociation service causes the following ++message to occur: ++ ++ Reassociation request ++ ++* Message type: Management ++* Message subtype: Reassociation request ++* Information items: ++ - IEEE address of the STA ++ - IEEE address of the AP with which the STA will reassociate ++ - IEEE address of the AP with which the STA is currently associated ++ - ESSID ++* Direction of message: From STA to 'new' AP ++ ++The address of the current AP is included for efficiency.

support" ++ select ZLIB_INFLATE ++ help ++ Saying Y here includes support for SquashFS 3.3 (a Compressed ++ Read-Only File System). Squashfs is a highly compressed read-only ++ filesystem for Linux. It uses zlib compression to compress both ++ files, inodes and directories. Inodes in the system are very small ++ and all blocks are packed to minimise data overhead. Block sizes ++ greater than 4K are supported up to a maximum of 1 Mbytes (default ++ block size 128K). SquashFS 3.3 supports 64 bit filesystems and files ++ (larger than 4GB), full uid/gid information, hard links and timestamps. ++ ++ Squashfs is intended for general read-only filesystem use, for ++ archival use (i.e. in cases where a .tar.gz file may be used), and in ++ embedded systems where low overhead is needed. Further information ++ and filesystem tools are available from http://squashfs.sourceforge.net. ++ ++ If you want to compile this as a module ( = code which can be ++ inserted in and removed from the running kernel whenever you want), ++ say M here and read <file:Documentation/modules.txt>. The module ++ will be called squashfs.
