* open/close
* 6.2.13 9/14/05

* accesses the FWSM that is not supported in other controllers
* 6.2.12 9/9/05
* 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 Enable fc by default on 82573 controllers (do not read eeprom)
* o Fix rx_errors statistic not to include missed_packet_count
* o Fix rx_dropped statistic not to include missed_packet_count

* 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
