| 5 | |
| 6 | History: |
| 7 | Feb 4 2002 - created initially by ShuChen <shuchen@realtek.com.tw>. |
| 8 | May 20 2002 - Add link status force-mode and TBI mode support. |
Francois Romieu | 5b0384f | 2006-08-16 16:00:01 +0200 | [diff] [blame] | 9 | 2004 - Massive updates. See kernel SCM system for details. |

| 11 | 1. [DEPRECATED: use ethtool instead] The media can be forced in 5 modes. |
| 12 | Command: 'insmod r8169 media = SET_MEDIA' |
| 13 | Ex: 'insmod r8169 media = 0x04' will force PHY to operate in 100Mpbs Half-duplex. |

| 24 | VERSION 1.1 <2002/10/4> |
| 25 | |
| 26 | The bit4:0 of MII register 4 is called "selector field", and have to be |
| 27 | 00001b to indicate support of IEEE std 802.3 during NWay process of |

Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 29 | |
| 30 | VERSION 1.2 <2002/11/30> |
| 31 | |
| 32 | - Large style cleanup |
| 33 | - Use ether_crc in stock kernel (linux/crc32.h) |
| 34 | - Copy mc_filter setup code from 8139cp |
| 35 | (includes an optimization, and avoids set_bit use) |
| 36 | |
| 37 | VERSION 1.6LK <2004/04/14> |
| 38 | |
| 39 | - Merge of Realtek's version 1.6 |
| 40 | - Conversion to DMA API |
| 41 | - Suspend/resume |
| 42 | - Endianness |
| 43 | - Misc Rx/Tx bugs |
| 44 | |
| 45 | VERSION 2.2LK <2005/01/25> |
| 46 | |
| 47 | - RX csum, TX csum/SG, TSO |
| 48 | - VLAN |
| 49 | - baby (< 7200) Jumbo frames support |
| 50 | - Merge of Realtek's version 2.2 (new phy) |
