Version 1.01a (jgarzik):
Version LK1.01a (jgarzik):
- Replace some MII-related magic numbers with constants
Version 1.02 (D-Link):
Version LK1.02 (D-Link):
- Add new board to PCI ID list
- Fix multicast bug
Version 1.03 (D-Link):
Version LK1.03 (D-Link):
- New Rx scheme, reduce Rx congestion
- Option to disable flow control
Version 1.04 (D-Link):
Version LK1.04 (D-Link):
- Tx timeout recovery
- More support for ethtool.
Version LK1.04a:
- Remove unused/constant members from struct pci_id_info
(which then allows removal of 'drv_flags' from private struct)
(jgarzik)
- If no phy is found, fail to load that board (jgarzik)
- Always start phy id scan at id 1 to avoid problems (Donald Becker)
- Autodetect where mii_preable_required is needed,
default to not needed. (Donald Becker)
Version LK1.04b:
- Remove mii_preamble_required module parameter (Donald Becker)
- Add per-interface mii_preamble_required (setting is autodetected)
(Donald Becker)
- Remove unnecessary cast from void pointer (jgarzik)
- Re-align comments in private struct (jgarzik)
Version LK1.04c (jgarzik):
- Support bitmapped message levels (NETIF_MSG_xxx), and the
two ethtool ioctls that get/set them
- Don't hand-code MII ethtool support, use standard API/lib
Version LK1.04d:
- Merge from Donald Becker's sundance.c: (Jason Lunz)
* proper support for variably-sized MTUs
* default to PIO, to fix chip bugs
- Add missing unregister_netdev (Jason Lunz)
- Add CONFIG_SUNDANCE_MMIO config option (jgarzik)
