Roflin 3905319aea PCB: insert MDI dampers R32-R35 in-line and place C20/C21 at J2 center taps
Insertion by Dennis; reviewed:
- DRC 0 errors / 0 unconnected / 0 schematic parity
- R32-R35 sit in-line between the termination cluster and D4/D5, each
  aligned to its own line row; MDI_* stubs only 1.45-1.48mm, no new
  vias, all pair copper at the ETH_DP 0.2mm width
- Pair skew after insertion: TX 0.66mm, RX 1.81mm - both far inside
  the 100BASE-TX budget
- C20/C21 placed against J2's pin column, about as close as the In1
  plane void allows while keeping short GND vias
