// Description:
// Provides wrapper for just the pieces specific to an MGT lane

//////////////////////////////////////////////////////////////////////
// Description:
//
// Wrapper for single MGT, including support for Aurora, WhiteRabbit, 10 GbE,
// and 1 GbE.
//
// Parameters:
//
// PROTOCOL : Must be "10GbE", "1GbE", "Aurora", or "Disabled".
// REG_DWIDTH : Data width of the AXI-Lite interface and RegPort
// REG_AWIDTH : Address width of the AXI-Lite interface and RegPort\
// GT_COMMON : Use GT Common ports on MGT
// PORTNUM : Port number
// MDIO_EN : Enables internal MDIO master
// MDIO_PHYADDR : Address to use for the MDIO
// RFNOC_PROTOVER : RFNoC protocol version to be reported by transport
// adapters.
// NODE_INST : RFNoC transport adapter node instance for this port
// EN_RX_KV_MAP_CFG : Enable KV-map configuration port on transport adapter
// EN_RX_RAW_PYLD : Enable raw UDP support on transport adapter
