- * o Add support for device id E1000_DEV_ID_82546GB_QUAD_COPPER
- * o set RCTL:SECRC only for controllers newer than 82543.
- * o When the n/w interface comes down reset DRV_LOAD bit to notify f/w.
- * This code was moved from e1000_remove to e1000_close
- * 6.2.10 9/6/05
- * o Fix error in updating RDT in el1000_alloc_rx_buffers[_ps] -- one off.

- * o Fix net_stats.rx_fifo_errors <p@draigBrady.com>
- * o Do not power off PHY if SoL/IDER session is active
- * 6.2.4 8/10/05
- * o Fix loopback test setup/cleanup for 82571/3 controllers
- * o Fix parsing of outgoing packets (e1000_transfer_dhcp_info) to treat
- * all packets as raw
- * o Prevent operations that will cause the PHY to be reset if SoL/IDER
- * sessions are active and log a message
- * 6.2.2 7/21/05
- * o used fixed size descriptors for all MTU sizes, reduces memory load
- * 6.1.2 4/13/05
- * o Fixed ethtool diagnostics
- * o Enabled flow control to take default eeprom settings
- * o Added stats_lock around e1000_read_phy_reg commands to avoid concurrent
- * calls, one from mii_ioctl and other from within update_stats while
- * processing MIIREG ioctl.
