This commit gets rid of a huge amount of silly white-space issues. Especially, all sequences of SPACEs followed by TAB characters get removed (unless they appear in print statements). Also remove all embedded "vim:" and "vi:" statements which hide indentation problems. Signed-off-by: Wolfgang Denk <wd@denx.de>

*
|
|
* @brief this file contains the public API of @ref IxEthMii component
|
|
*
|
|
* Design notes :
|
|
* The main intent of this API is to inplement MII high level fonctionalitoes
|
|
* to support the codelets provided with the IXP400 software releases. It
|
|
* superceedes previous interfaces provided with @ref IxEThAcc component.
|
|
*
|
|
* This API has been tested with the PHYs provided with the
|
|
* IXP400 development platforms. It may not work for specific Ethernet PHYs
|
|
* used on specific boards.
|
|
*
|
|
* This source code detects and interface the LXT972, LXT973 and KS6995
|
|
* Ethernet PHYs.
|
|
*
|
|
* This source code should be considered as an example which may need
|
|
* to be adapted for different hardware implementations.
|
|
*
|
|
* It is strongly recommended to use public domain and GPL utilities
|
|
* like libmii, mii-diag for MII interface support.
