802.11 Reference Design version 1.4.0 FPGA Architecture for WARP v3 Hardware

The 802.11 Reference Design version 1.4.0 for WARP v3 makes changes to the underlying FPGA architecture. This includes:

• New MAC time hardware core
• Updates to Ethernet hardware (makes ETH A and ETH B equivalent)
• Updates to peripheral address map
• See changelog for other updates
