From: Roy Zang <tie-fei.zang at freescale.com>
Based on Intel PRO/1000 Network Driver 7.3.20-k2
Add Intel E1000 PCIE card support. The following cards are added:
INTEL_82571EB_COPPER
INTEL_82571EB_FIBER,
INTEL_82571EB_SERDES
INTEL_82571EB_QUAD_COPPER
INTEL_82571PT_QUAD_COPPER
INTEL_82571EB_QUAD_FIBER
INTEL_82571EB_QUAD_COPPER_LOWPROFILE
INTEL_82571EB_SERDES_DUAL
INTEL_82571EB_SERDES_QUAD
INTEL_82572EI_COPPER
INTEL_82572EI_FIBER
INTEL_82572EI_SERDES
INTEL_82572EI
INTEL_82573E
INTEL_82573E_IAMT
INTEL_82573L
INTEL_82546GB_QUAD_COPPER_KSP3
INTEL_80003ES2LAN_COPPER_DPT
INTEL_80003ES2LAN_SERDES_DPT
INTEL_80003ES2LAN_COPPER_SPT
INTEL_80003ES2LAN_SERDES_SPT
82571EB_COPPER dual ports,
82572EI single port,
82572EI_COPPER single port PCIE cards
and
82545EM_COPPER,
82541GI_LF
pci cards are tested on both P2020 board
and MPC8544DS board.
