dsa: Hide core config options; make drivers select what they need Commit 82167cb8c6b2f8166d5c7532e5ef4b5e0cc46a72 ('net: dsa/slave: Fix compilation warnings') fixed one possible invalid configuration (NET_DSA enabled with no trailer formats) but added others: drivers can select NET_DSA without its dependencies being met. It's not very useful to make either the DSA core or the tagging formats manually selectable without a driver to use them, so: 1. Define a hidden HAVE_NET_DSA option and move the dependencies of NET_DSA to that. While we're at it, drop the deprecated EXPERIMENTAL dependency. 2. Make NET_DSA and the drivers dependent on HAVE_NET_DSA. 3. Hide the tagging format options again. 4. Make drivers select both NET_DSA and the appropriate tagging format option.

net: Distributed Switch Architecture protocol support Distributed Switch Architecture is a protocol for managing hardware switch chips. It consists of a set of MII management registers and commands to configure the switch, and an ethernet header format to signal which of the ports of the switch a packet was received from or is intended to be sent to.

This initial patch supports the MII management interface register layout of the Marvell 88E6123, 88E6161 and 88E6165 switch chips, and supports the "Ethertype DSA" packet tagging format. (There is no officially registered ethertype for the Ethertype DSA packet format, so we just grab a random one.

In other words, when receiving a packet that is tagged with an original DSA tag, there is no way of telling in eth_type_trans() that this packet is in fact a DSA-tagged packet.

dsa: Hide core config options; make drivers select what they need Commit 82167cb8c6b2f8166d5c7532e5ef4b5e0cc46a72 ('net: dsa/slave: Fix compilation warnings') fixed one possible invalid configuration (NET_DSA enabled with no trailer formats) but added others: drivers can select NET_DSA without its dependencies being met. It's not very useful to make either the DSA core or the tagging formats manually selectable without a driver to use them, so: 1. Define a hidden HAVE_NET_DSA option and move the dependencies of NET_DSA to that. While we're at it, drop the deprecated EXPERIMENTAL dependency. 2. Make NET_DSA and the drivers dependent on HAVE_NET_DSA. 3. Hide the tagging format options again. 4. Make drivers select both NET_DSA and the appropriate tagging format option.
