Commit c0e1c9e4 authored by Scott Feldman's avatar Scott Feldman Committed by David Mosberger

Update e100 net driver:

o Added device ID support for Dell LOM.
o Added device ID support for 82511QM mobile nics.
o Bug fix: ethtool get/set EEPROM routines modified to use byte
  addressing rather than word addressing.
o Feature: added MDIX mode support for 82550 and up.
o Bug fix: added reboot notifier to setup WOL settings when
  shutting system down.
o Cleanup: removed yield() redefinition (Andrew Morton,
  akpm@zip.com.au).
o Bug fix: flow control now working when link partner is
  autoneg capable but not flow control capable.
o Bug fix: added check for corrupted EEPROM
o Bug fix: don't report checksum offloading for the older
  controllers that don't support the feature.
o Bug fix: calculate cable diagnostics when link goes down
  rather than when queuering /proc file.
o Cleanup: move mdi_access_lock to local get/set mdi routines.
