Subject: [PATCH net 0/4] Fixes for SJA1105 DSA tc-gate action

From: Vladimir Oltean <vladimir.oltean@....com>

This small series fixes 2 bugs in the tc-gate implementation:
1. The TAS state machine keeps getting rescheduled even after removing
   tc-gate actions on all ports.
2. tc-gate actions with only one gate control list entry are installed
   to hardware with an incorrect interval of zero, which makes the
   switch erroneously drop those packets (since the configuration is
   invalid).

To keep the code palatable, a forward-declaration was avoided by moving
some code around in patch 1/4. I hope that isn't too much of an issue.
