* 0.47: 26 Oct 2005: Add phyaddr 0 in phy scan.
* 0.48: 24 Dec 2005: Disable TSO, bugfix for pci_map_single
* 0.49: 10 Dec 2005: Fix tso for large buffers.
- * 0.50: 20 Jan 2006: Add 8021pq tagging support.
- * 0.51: 20 Jan 2006: Add 64bit consistent memory allocation for rings.
- * 0.52: 20 Jan 2006: Add MSI/MSIX support.
- * 0.53: 19 Mar 2006: Fix init from low power mode and add hw reset.
- * 0.54: 21 Mar 2006: Fix spin locks for multi irqs and cleanup.
*
* Known bugs:
* We suspect that on some hardware no TX done interrupts are generated.
* DEV_NEED_TIMERIRQ will not harm you on sane hardware, only generating a few
* superfluous timer interrupts from the nic.
