+ [link no longer provides useful info -jgarzik]
- Linux kernel modifications:
-
- Version 1.0.1:
- - Spinlock fixes
- - Bug fixes and better intr performance (Tjeerd)
- Version 1.0.2:
- - Now reads correct MAC address from eeprom
- Version 1.0.3:
- - Eliminate redundant priv->tx_full flag
- - Call netif_start_queue from dev->tx_timeout
- - wmb() in start_tx() to flush data
- - Update Tx locking
- - Clean up PCI enable (davej)
- Version 1.0.4:
- - Merge Donald Becker's natsemi.c version 1.07
- Version 1.0.5:
- - { fill me in }
- Version 1.0.6:
- * ethtool support (jgarzik)
- * Proper initialization of the card (which sometimes
- fails to occur and leaves the card in a non-functional
- state). (uzi)
-
- * Some documented register settings to optimize some
- of the 100Mbit autodetection circuitry in rev C cards. (uzi)
-
- * Polling of the PHY intr for stuff like link state
- change and auto- negotiation to finally work properly. (uzi)
-
- * One-liner removal of a duplicate declaration of
- netdev_error(). (uzi)
-
- Version 1.0.7: (Manfred Spraul)
- * pci dma
- * SMP locking update
- * full reset added into tx_timeout
- * correct multicast hash generation (both big and little endian)
- [copied from a natsemi driver version
- from Myrio Corporation, Greg Smith]
- * suspend/resume
-
- version 1.0.8 (Tim Hockin <thockin@sun.com>)
- * ETHTOOL_* support
- * Wake on lan support (Erik Gilling)
- * MXDMA fixes for serverworks
- * EEPROM reload
-
- version 1.0.9 (Manfred Spraul)
- * Main change: fix lack of synchronize
- netif_close/netif_suspend against a last interrupt
- or packet.
- * do not enable superflous interrupts (e.g. the
- drivers relies on TxDone - TxIntr not needed)
- * wait that the hardware has really stopped in close
- and suspend.
- * workaround for the (at least) gcc-2.95.1 compiler
- problem. Also simplifies the code a bit.
- * disable_irq() in tx_timeout - needed to protect
- against rx interrupts.
- * stop the nic before switching into silent rx mode
- for wol (required according to docu).
-
- version 1.0.10:
- * use long for ee_addr (various)
- * print pointers properly (DaveM)
- * include asm/irq.h (?)
-
- version 1.0.11:
- * check and reset if PHY errors appear (Adrian Sun)
- * WoL cleanup (Tim Hockin)
- * Magic number cleanup (Tim Hockin)
- * Don't reload EEPROM on every reset (Tim Hockin)
- * Save and restore EEPROM state across reset (Tim Hockin)
- * MDIO Cleanup (Tim Hockin)
- * Reformat register offsets/bits (jgarzik)
-
- version 1.0.12:
- * ETHTOOL_* further support (Tim Hockin)
-
- version 1.0.13:
- * ETHTOOL_[G]EEPROM support (Tim Hockin)
-
- version 1.0.13:
- * crc cleanup (Matt Domsch <Matt_Domsch@dell.com>)
-
- version 1.0.14:
- * Cleanup some messages and autoneg in ethtool (Tim Hockin)
-
- version 1.0.15:
- * Get rid of cable_magic flag
- * use new (National provided) solution for cable magic issue
-
- version 1.0.16:
- * call netdev_rx() for RxErrors (Manfred Spraul)
- * formatting and cleanups
- * change options and full_duplex arrays to be zero
- initialized
- * enable only the WoL and PHY interrupts in wol mode
-
- version 1.0.17:
- * only do cable_magic on 83815 and early 83816 (Tim Hockin)
- * create a function for rx refill (Manfred Spraul)
- * combine drain_ring and init_ring (Manfred Spraul)
- * oom handling (Manfred Spraul)
- * hands_off instead of playing with netif_device_{de,a}ttach
- (Manfred Spraul)
- * be sure to write the MAC back to the chip (Manfred Spraul)
- * lengthen EEPROM timeout, and always warn about timeouts
- (Manfred Spraul)
- * comments update (Manfred)
- * do the right thing on a phy-reset (Manfred and Tim)
-

* big endian support with CFG:BEM instead of cpu_to_le32
