tio: accept VIRTIO_NET_HDR_GSO_ECN-qualified superpackets
...
TUN_F_TSO_ECN is negotiated, so once ECN feedback flows the kernel hands
us TSO superpackets typed TCPV4|GSO_ECN (CWR set). protoFromGSOType
treated the qualifier bit as an unknown type and the read path dropped
every such superpacket - a latent bug that only fires when a congested
hop CE-marks the flow, exactly when drops hurt most. The segmenter
already handles CWR (first segment only); just mask the bit.

datapath: fix 12 correctness findings from tun/UDP offload review
...
Multi-disciplinary correctness review of the batched tun / GSO-GRO / sendmmsg
rework. Each fix has a regression test; the merged tree builds on
linux/darwin/openbsd/windows/freebsd/netbsd, vets clean, passes the unit and
e2e suites, and is -race clean.
Critical:
- C1 zero-length inner UDP datagram no longer panics the process (remote DoS):
the UDP coalescer routes payLen==0 to passthrough instead of seeding a GSO
slot, and WriteGSO skips empty payload iovecs as defense in depth.
- C2 segmenter no longer corrupts inner headers when gsoSize < headerLen: the
L3+L4 header is snapshotted once and each segment stamped from the copy,
replacing the destructive overlapping in-place slide (SegmentTCP + SegmentUDP).
High:
- H1 applyOuterECN updates the IPv4 header checksum (RFC 1624 incremental) when
folding outer CE into the inner ToS, so passthrough packets are no longer
dropped by the peer stack.
- H2 the GRO reject path caps the borrowed RX segment ([:n:n]) so a reject can
no longer overrun into the next coalesced segment's Nebula header. Note:
oversized ICMPv6 rejects that need >16B beyond the segment are now refused
rather than sent under GRO (safe; see TOFIX.md for the scratch-buffer follow-up).
- H3 WriteBatch falls back to per-packet WriteTo for a chunk when writeSockaddr
fails, so one bad-family destination costs only its own packet, not the batch.
- H4 UserDevice.Readers returns N distinct queue wrappers with private buffers
(sharing the pipes) so concurrent readers no longer race/overwrite borrowed
packet bytes.
- H5 Poll.Close / Offload.Close no longer null t.fd (matching master's
tunFile.Close), removing the data race with a concurrent readOne load.
Medium/Low:
- M1 the UDP GSO 127-segment gate moved from kernel >=5.5 to >=6.9 (the real
UDP_MAX_SEGMENTS 64->128 threshold), avoiding EINVAL + per-packet fallback on
5.5-6.8 kernels.
- M2 NewMultiQueueReader replays the offload mask newTun actually negotiated
instead of the TSO-only mask, so adding a queue no longer disables USO
device-wide; the advertised USO capability derives from the same mask.
- M3 the shutdown eventfd is closed in pollQueueSet.Close / offloadQueueSet.Close
(double-close guarded), fixing the per-lifecycle fd leak.
- M4 dual-stack ECN selects the cmsg by address family, not socket family: RX
parseRecvCmsg reads both IP_TOS and IPV6_TCLASS; TX writeEntryCmsg stamps
IP_TOS for v4/v4-mapped dests and IPV6_TCLASS for v6 (on-host verified).
- L1 newPoll no longer closes the fd on failure (matching newOffload), removing
the double-close on QueueSet.Add error.
