LinkDevice trait gains is_promiscuous() and set_promiscuous().
EthernetLink stores promiscuous flag (default: false).
Receive path bypasses MAC check when promiscuous enabled —
captures all frames regardless of destination MAC.
netcfg/ifaces/eth0/promiscuous rw:
cat /scheme/netcfg/ifaces/eth0/promiscuous → 'off' or 'on'
echo on > .../promiscuous → enable promiscuous mode
echo off > .../promiscuous → disable
Accepts: on/off/1/0/yes/no/true/false.
Mirrors Linux 'ip link set dev promisc on/off'.
Required for packet capture tools that need to see all traffic.
