- *
|
|
- * 6.0.44+ 2/15/05
|
|
- * o Added code to handle raw packet based DHCP packets
|
|
- * o Added code to fix the errata 10 buffer overflow issue
|
|
- * o Sync up with WR01-05
|
|
- * o applied Anton's patch to resolve tx hang in hardware
|
|
- * o iegbe timeouts with early writeback patch
|
|
- * o Removed Queensport IDs
|
|
- * o fixed driver panic if MAC receives a bad large packets when packet
|
|
- * split is enabled
|
|
- * o Applied Andrew Mortons patch - iegbe stops working after resume
|
|
- * 5.2.29 12/24/03
|
|
- * o Bug fix: Endianess issue causing ethtool diags to fail on ppc.
|
|
- * o Bug fix: Use pdev->irq instead of netdev->irq for MSI support.
|
|
- * o Report driver message on user override of InterruptThrottleRate module
|
|
- * parameter.
|
|
- * o Bug fix: Change I/O address storage from uint32_t to unsigned long.
|
|
- * o Feature: Added ethtool RINGPARAM support.
|
|
- * o Feature: Added netpoll support.
|
|
- * o Bug fix: Race between Tx queue and Tx clean fixed with a spin lock.
|
|
- * o Bug fix: Allow 1000/Full setting for autoneg param for fiber connections.
|
|
- * Jon D Mason [jonmason@us.ibm.com].
|
|
- *
|
|
- * 5.2.22 10/15/03
|
|
- * o Bug fix: SERDES devices might be connected to a back-plane switch that
|
|
- * doesn't support auto-neg, so add the capability to force 1000/Full.
|
|
- * Also, since forcing 1000/Full, sample RxSynchronize bit to detect link
|
|
- * state.
|
|
- * o Bug fix: Flow control settings for hi/lo watermark didn't consider
|
|
- * changes in the RX FIFO size, which could occur with Jumbo Frames or with
|
|
- * the reduced FIFO in 82547.
|
|
- * o Bug fix: Better propagation of error codes.
|
|
- * [Janice Girouard (janiceg -a-t- us.ibm.com)]
|
|
- * o Bug fix: hang under heavy Tx stress when running out of Tx descriptors;
|
|
- * wasn't clearing context descriptor when backing out of send because of
|
|
- * no-resource condition.
|
|
- * o Bug fix: check netif_running in dev->poll so we don't have to hang in
|
|
- * dev->close until all polls are finished. [Rober Olsson
|
|
- * (robert.olsson@data.slu.se)].
|
|
- * o Revert TxDescriptor ring size back to 256 since change to 1024 wasn't
|
|
- * accepted into the kernel.
