Clarification about dsa and ipq806x

[Ansuel Smith]

Hello,
I just pushed a fist pr to the openwrt github repo for ipq806x port to
kernel 5.10.
The idea is to switch this target to dsa but there is a problem...
Since kernel 5.10 is a testing kernel how should I change the base
files to apply different network config?
Kernel 5.4 would still use the old swconfig driver and the dsa driver
still lacks vlan support in kernel 5.4.
Do we have some way in openwrt to know if the system use dsa driver or
swconfig driver?
