Support and updates available at
http://www.scyld.com/network/sundance.html
-
-
- Version LK1.01a (jgarzik):
- - Replace some MII-related magic numbers with constants
-
- Version LK1.02 (D-Link):
- - Add new board to PCI ID list
- - Fix multicast bug
-
- Version LK1.03 (D-Link):
- - New Rx scheme, reduce Rx congestion
- - Option to disable flow control
-
- 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)
- - Better rx buf size calculation (Donald Becker)
-
- Version LK1.05 (D-Link):
- - Fix DFE-580TX packet drop issue (for DL10050C)
- - Fix reset_tx logic
-
- Version LK1.06 (D-Link):
- - Fix crash while unloading driver
-
- Versin LK1.06b (D-Link):
- - New tx scheme, adaptive tx_coalesce
-
- Version LK1.07 (D-Link):
- - Fix tx bugs in big-endian machines
- - Remove unused max_interrupt_work module parameter, the new
- NAPI-like rx scheme doesn't need it.
- - Remove redundancy get_stats() in intr_handler(), those
- I/O access could affect performance in ARM-based system
- - Add Linux software VLAN support
-
- Version LK1.08 (D-Link):
- - Fix bug of custom mac address
- (StationAddr register only accept word write)
-
- Version LK1.09 (D-Link):
- - Fix the flowctrl bug.
- - Set Pause bit in MII ANAR if flow control enabled.
-
- Version LK1.09a (ICPlus):
- - Add the delay time in reading the contents of EEPROM
+ [link no longer provides useful info -jgarzik]
