14ec4a02dd tunnel: buffer WriteFrames into single TLS write 
Assemble numBlocks + frame sizes + frame data into one buffer before
writing. Reduces TLS records and syscalls from 3 per frame to 1.

b3f4c5f42b tunnel: add write mutex for concurrent safety 
WriteFrames and keepalive both write multi-part messages to the TLS
connection. Without synchronization, their writes could interleave
and corrupt the framing. Add writeMu to serialize all tunnel writes.

bbeeb8c41b tunnel: document TAP goroutine lifecycle on disconnect 
The TAP→Server goroutine can't be interrupted (TAP fd doesn't support
deadlines). It exits on next TAP frame when WriteFrames fails on the
closed connection. Document this rather than add complexity.

b2ef8bc1bf tunnel: reduce per-frame allocations in hot path 
- TAP→server: write buf[:n] directly instead of copy to new slice
- Keepalive: reuse fixed buffer instead of allocating every 3s

17c1063e1f refactor: extract session/netcfg/tunnel, add mac/dhcp/policy-route flags 
- Split cmd/softether-go into main.go (flags, reconnect loop) and
  session.go (session lifecycle, DHCP orchestration)
- Extract network config to pkg/netcfg (TAP config, routing, DNS, policy routes)
- Move frame bridging to pkg/client/tunnel.go as Bridge() method
- Add -mac, -dhcp, -policy-route-table CLI flags
- Add SetMAC() to pkg/tap for deterministic DHCP assignments
- Update all docs to reflect new structure and flags
