docs: net: dsa: remove references to struct dsa_device_ops::filter

Browse source 
This function has disappeared in commit edac6f6332 ("Revert "net: dsa:
Allow drivers to filter packets they can decode source port from"").

Also, since commit 4e50025129 ("net: dsa: generalize overhead for
taggers that use both headers and trailers"), the next paragraph is no
longer true (it is still discouraged to do that, but it is now
supported, so no point in mentioning it). Delete.

@ -200,19 +200,6 @@ receive all frames regardless of the value of the MAC DA. This can be done by
setting the ``promisc_on_master`` property of the ``struct dsa_device_ops``.
Note that this assumes a DSA-unaware master driver, which is the norm.
Hardware manufacturers are strongly discouraged to do this, but some tagging
protocols might not provide source port information on RX for all packets, but
e.g. only for control traffic (link-local PDUs). In this case, by implementing
the ``filter`` method of ``struct dsa_device_ops``, the tagger might select
which packets are to be redirected on RX towards the virtual DSA user network
interfaces, and which are to be left in the DSA master's RX data path.
It might also happen (although silicon vendors are strongly discouraged to
produce hardware like this) that a tagging protocol splits the switch-specific
information into a header portion and a tail portion, therefore not falling
cleanly into any of the above 3 categories. DSA does not support this
configuration.
