I looked into this more:

~/d/o/t/linux (master)> git grep CONFIG_SWCONFIG=y
apm821xx/nand/config-default:CONFIG_SWCONFIG=y
ath25/config-5.4:CONFIG_SWCONFIG=y
ath79/config-5.4:CONFIG_SWCONFIG=y
bcm47xx/config-5.4:CONFIG_SWCONFIG=y
bcm53xx/config-5.4:CONFIG_SWCONFIG=y
bcm63xx/config-5.4:CONFIG_SWCONFIG=y
ipq40xx/config-5.4:CONFIG_SWCONFIG=y
ipq806x/config-5.4:CONFIG_SWCONFIG=y
ipq807x/config-default:CONFIG_SWCONFIG=y
lantiq/config-5.4:CONFIG_SWCONFIG=y
mediatek/mt7622/config-5.4:CONFIG_SWCONFIG=y
mediatek/mt7623/config-5.4:CONFIG_SWCONFIG=y
mediatek/mt7629/config-5.4:CONFIG_SWCONFIG=y
mpc85xx/config-5.4:CONFIG_SWCONFIG=y
ramips/mt7620/config-5.4:CONFIG_SWCONFIG=y
ramips/mt76x8/config-5.4:CONFIG_SWCONFIG=y
ramips/rt288x/config-5.4:CONFIG_SWCONFIG=y
ramips/rt305x/config-5.4:CONFIG_SWCONFIG=y
ramips/rt3883/config-5.4:CONFIG_SWCONFIG=y
rtl838x/config-5.4:CONFIG_SWCONFIG=y
sunxi/config-5.4:CONFIG_SWCONFIG=y

mt7628 seems to have DSA support upstream. kirkwood is not there.

ath79/tiny/config-default:CONFIG_NET_DSA=y
gemini/config-5.4:CONFIG_NET_DSA=y
imx6/config-5.4:CONFIG_NET_DSA=y
ipq806x/config-5.4:CONFIG_NET_DSA=y
kirkwood/config-5.4:CONFIG_NET_DSA=y
mediatek/mt7622/config-5.4:CONFIG_NET_DSA=y
mediatek/mt7623/config-5.4:CONFIG_NET_DSA=y
mvebu/config-5.4:CONFIG_NET_DSA=y
octeon/config-5.4:CONFIG_NET_DSA=y
ramips/mt7621/config-5.4:CONFIG_NET_DSA=y
rtl838x/config-5.4:CONFIG_NET_DSA=y

is the DSA stuff.

Some of the swconfig targets can be ported. For example I remember
using a DSA patch for a Netgear R7800.
