+"""Decode an iwlwifi host-command trace captured from Linux on the same adapter.
+
+Linux drives this exact firmware successfully, so its host commands are ground
+truth for what the firmware expects -- far more reliable than reading struct
+definitions out of a kernel tree and hoping the version matches.
+
+Capture on a Linux box with the adapter, as root:
+
+  trace-cmd record -e iwlwifi_dev_hcmd -o /tmp/iwl.dat \
+      sh -c 'nmcli radio wifi off; sleep 2; nmcli radio wifi on; sleep 20'
+
+Then run this against /tmp/iwl.dat.  dump_iwl_cmds.py prints full payload hex
+for each command instead of a decoded summary.
