syzygy-sgmii: Breakout board for SGMII Gigabit Ethernet PHY DP83867C

This design is a breakout board for SGMII Gigabit Ethernet PHY DP83867C. It connects to SERDES via a SYZYGY-TXR connector to test and evaluate Ethernet over 1.25Gbps serial channels. 2 channels are used and CDR is required on the RX path. Compared to RGMII, SGMII significantly reduces the number of signals required for routing.
