Subject: [PATCH] rtlwifi: btcoex: add routine to set default port id
Git-commit: d7297a86fc86d1e373c2f26e3c1cfcf7b6129217
Patch-mainline: v4.17-rc1
References: FATE#326906

Tell wifi and BT firmware the default port ID to set multiports' state
properly, but only 8822be needs this function currently.
