-        # so it knows to open multiple TCP streams. The capability tag
-        # format is:
-        #   <ip-or-iface>;capability=<flags>,speed=<bits/s>
-        # Flags:
-        #   RSS     — NIC has receive-side scaling (multi-queue), so
-        #             multiple client→server streams will spread across
-        #             cores on the server. macOS Sequoia uses this hint
-        #             to open up to 32 channels per session.
-        #   DYNAMIC — loopback only; client should not use for traffic.
-        # speed= is informational, advertised back to the client so it
-        # can prefer fast paths if multiple are offered. 80 Gbps = bond
-        # aggregate of 2× 40 GbE LACP slaves.
-        #
-        # Even though bond40g is a single LACP-managed device, the LACP
-        # layer3+4 xmit hash distributes the multichannel TCP streams
-        # across both slaves transparently. Net effect ≈ 2-4× SMB
-        # throughput vs a single channel, no client-side config needed.

+        # but Samba's parser split on semicolons too aggressively and

+        # and broke auth (rpcd_classic crash-looped on disconnected
+        # endpoints, smbd rejected all client auth as `Authentication
+        # error`). Reverted 2026-05-16. Clients still get multichannel
+        # support via `server multi channel support`; they just open
+        # one channel by default without the RSS hint. Re-enable
+        # capability advertising only with a verified working syntax.
