/* Change Log
*
* 5.2.51 5/14/04
* o set default configuration to 'NAPI disabled'. NAPI enabled driver
* causes kernel panic when the interface is shutdown while data is being
* transferred.
* 5.2.47 5/04/04
* o fixed ethtool -t implementation
* 5.2.45 4/29/04
* o fixed ethtool -e implementation
* o Support for ethtool ops [Stephen Hemminger (shemminger@osdl.org)]
* 5.2.42 4/26/04
* o Added support for the DPRINTK macro for enhanced error logging. Some
* parts of the patch were supplied by Jon Mason.
* o Move the register_netdevice() donw in the probe routine due to a
* loading/unloading test issue.
* o Added a long RX byte count the the extra ethtool data members for BER
* testing purposes.
* 5.2.39 3/12/04
* o Added support to read/write eeprom data in proper order.
* By default device eeprom is always little-endian, word
* addressable
* o Disable TSO as the default for the driver until hangs
* reported against non-IA acrhs can be root-caused.
* o Back out the CSA fix for 82547 as it continues to cause
* systems lock-ups with production systems.
* o Fixed FC high/low water mark values to actually be in the
* range of the Rx FIFO area. It was a math error.
* [Dainis Jonitis (dainis_jonitis@exigengroup.lv)]
* o Handle failure to get new resources when doing ethtool
* ring paramater changes. Previously, driver would free old,
* but fails to allocate new, causing problems. Now, driver
* allocates new, and if sucessful, frees old.
* o Changed collision threshold from 16 to 15 to comply with IEEE
* spec.
* o Toggle chip-select when checking ready status on SPI eeproms.
* o Put PHY into class A mode to pass IEEE tests on some designs.
* Designs with EEPROM word 0x7, bit 15 set will have their PHYs
* set to class A mode, rather than the default class AB.
* o Handle failures of register_netdev. Stephen Hemminger
* [shemminger@osdl.org].
* o updated README & MAN pages, number of Transmit/Receive
* descriptors may be denied depending on system resources.
*
* 5.2.30 1/14/03
* o Set VLAN filtering to IEEE 802.1Q after reset so we don't break
* SoL connections that use VLANs.
* o Allow 1000/Full setting for AutoNeg param for Fiber connections
* Jon D Mason [jonmason@us.ibm.com].
* o Race between Tx queue and Tx clean fixed with a spin lock.
* o Added netpoll support.
* o Fixed endianess bug causing ethtool loopback diags to fail on ppc.
* o Use pdev->irq rather than netdev->irq in preparation for MSI support.
* o Report driver message on user override of InterruptThrottleRate
* module parameter.
* o Change I/O address storage from uint32_t to unsigned long.
* o Added ethtool RINGPARAM support.
*
* 5.2.22 10/15/03
