MII PHY support

Features not supported

  • The following features are not supported:
    • MCDMA
    • 10G/25G MAC
  • There is no support for common MDIO bus for two GEMs on lwip. For ex., on VCK190 board, GEM0 can be used with TI PHY (at PHY address 1) via the dedicated MDIO0 bus but GEM1 cannot be used with TI PHY at PHY address 2 via the common MDIO0.

Performance

These benchmark performance numbers were obtained by connecting Xilinx boards to Linux PCs/server machines (Ubuntu/Red Hat Enterprise).
The application used is the lwip SW app (see test cases below) with optimal settings on the board side. iperf is run on the linux machine.
