Detailed Description

Runtime state of the R-Switch model.

win is the flat register shadow for the whole window (config registers read back what was written). linkfix_base captures GWDCBAC1 so the DMA can find the descriptor rings; rx_queue is the queue index the driver configured for reception (GWDCC.DQT == 0). phy holds the modelled Clause-22 PHY register file. The counters mirror MTGFCE / MRFC / MRGFCE.
