net: dsa: tag_ocelot: convert to tagger-owned data
The felix driver makes very light use of dp->priv, and the tagger is effectively stateless. dp->priv is practically only needed to set up a callback to perform deferred xmit of PTP and STP packets using the ocelot-8021q tagging protocol (the main ocelot tagging protocol makes no use of dp->priv, although this driver sets up dp->priv irrespective of actual tagging protocol in use). struct felix_port (what used to be pointed to by dp->priv) is removed and replaced with a two-sided structure. The public side of this structure, visible to the switch driver, is ocelot_8021q_tagger_data. The private side is ocelot_8021q_tagger_private, and the latter structure physically encapsulates the former. The public half of the tagger data structure can be accessed through a helper of the same name (ocelot_8021q_tagger_data) which also sanity-checks the protocol currently in use by the switch. The public/private split was requested by Andrew Lunn. Suggested-by:Andrew Lunn <andrew@lunn.ch> Signed-off-by:
