====================
Documentation: dsa: misc fixes

Here are some miscelaneous documentation fixes for DSA, I targeted "net"
because these are not functional code changes, but still documentation fixes
per-se.

Changes in v2:

- reword what the port_vlan_filtering is about based on feedback from Vivien and Ido

Bridge VLAN filtering
---------------------
- port_vlan_filtering: bridge layer function invoked when the bridge gets
configured for turning on or off VLAN filtering. If nothing specific needs to
be done at the hardware level, this callback does not need to be implemented.
When VLAN filtering is turned on, the hardware must be programmed with
rejecting 802.1Q frames which have VLAN IDs outside of the programmed allowed
VLAN ID map/rules. If there is no PVID programmed into the switch port,
untagged frames must be rejected as well. When turned off the switch must
accept any 802.1Q frames irrespective of their VLAN ID, and untagged frames are
allowed.
- port_vlan_prepare: bridge layer function invoked when the bridge prepares the
configuration of a VLAN on the given port. If the operation is not supported
by the hardware, this function should return -EOPNOTSUPP to inform the bridge
