* Tigran Aivazian <tigran@sco.com>: TLan_PciProbe() now uses
* new PCI BIOS interface.
- * Alan Cox <alan@redhat.com>: Fixed the out of memory
+ * Alan Cox <alan@lxorguk.ukuu.org.uk>:
+ * Fixed the out of memory
* handling.
*
* Torben Mathiasen <torben.mathiasen@compaq.com> New Maintainer!
* v1.15 Apr 4, 2002 - Correct operation when aui=1 to be
* 10T half duplex no loopback
* Thanks to Gunnar Eikman
+ *
+ * Sakari Ailus <sakari.ailus@iki.fi>:
+ *
+ * v1.15a Dec 15 2008 - Remove bbuf support, it doesn't work anyway.
