docs: networkng: convert sja1105's devlink info to RTS
A new file snuck into the tree after all existing documentation was converted to RST. Convert sja1105's devlink info and move it where the rest of the drivers are documented.

-best_effort_vlan_filtering
- [DEVICE, DRIVER-SPECIFIC]
- Allow plain ETH_P_8021Q headers to be used as DSA tags.
- Benefits:
- - Can terminate untagged traffic over switch net
- devices even when enslaved to a bridge with
- vlan_filtering=1.
- - Can terminate VLAN-tagged traffic over switch net
- devices even when enslaved to a bridge with
- vlan_filtering=1, with some constraints (no more than
- 7 non-pvid VLANs per user port).
- - Can do QoS based on VLAN PCP and VLAN membership
- admission control for autonomously forwarded frames
- (regardless of whether they can be terminated on the
- CPU or not).
- Drawbacks:
- - User cannot use VLANs in range 1024-3071. If the
- switch receives frames with such VIDs, it will
- misinterpret them as DSA tags.
- - Switch uses Shared VLAN Learning (FDB lookup uses
- only DMAC as key).
- - When VLANs span cross-chip topologies, the total
- number of permitted VLANs may be less than 7 per
- port, due to a maximum number of 32 VLAN retagging
- rules per switch.
- Configuration mode: runtime
- Type: bool.
