- This driver is for RDC R6040 FastEthernet MAC series.
- For kernel version after 2.4.22
-
- Modification List
- ---------- ------------------------------------------------
- 10-07-2007 Clean up the driver using checkpatch
- 08-24-2006 Support at linux 2.6.10 above
- 03-24-2006 Support NAPI
- 03-21-2006 By Charies,change spin_lock_irqsave(lp->lock, flags)
- to spin_lock_irqsave(&lp->lock, flags)
- in set_multicast_list
- 03-15-2006 Modify the set_multicast_list ,due to when re-plug the ethernet,
- it will forget the previous setting
- 07-12-2005 Tim, modify the set_multicast_list
- 03-28-2005 Tim, modify some error mac register offset in
- function set_multicast_list
- 03-27-2005 Tim, Add the internal state machine reset
- Sten, If multicast address more than 4, enter PROM mode
- Changed rdc to r6040
- 12-22-2004 Sten Init MAC MBCR register=0x012A
- PHY_CAP = 0x01E1
-
- Need to Do LIst:
- 1. If multicast address more than 4, use the multicast address hash
