net: keep network packets out of the console (fixes shell garbage on netboot)
The link port is both the console-input fallback and the network. At the shell
prompt the host's multicast (mDNS/LLMNR/IGMP) was fed to the serial and KGetc
read those packet bytes as console input -> garbage in the shell, OSK unusable.
Two-part fix:
- KGetc now skips SLIP frames (0xC0-delimited) on the serial console path, so
inbound packets never surface as console input. Plain injected bytes (the
headless tunbridge command path) still pass through. New wConInSkip flag.
- netboot/tunbridge only forward IP packets destined to 10.0.0.2 (drop the
multicast noise at the bridge).
Verified: GB sits at a clean "/#" prompt while all packets (noise included) are
forwarded; being-pinged (3/3) and wget still work. On the emulator, the OSK is
SELECT=space, START=enter, A=z, B=x, d-pad=WASD/arrows.
