stp: enforce blocking on unicast send + enhanced stats display

Browse Source 
BridgeDevice STP hardening:
- send(): check STP blocking before unicast forwarding (host-originated)
- recv(): check STP blocking before unicast forwarding (switched frames)
- Previously only flood() checked STP; unicast forwarding bypassed it.
  A blocked port must never forward any traffic — STP semantics now correct.

netcfg stats enhancement:
- Per-interface stats now include mtu= and link= fields alongside counters
- Applies to both eth0 and loopback
- Enables bandwidth monitoring tools to self-discover MTU/link state
