No. msk(4) supports Marvell Yukon II controllers.

No. Backporting msk(4) from stable/8 and stable/7 to 6.1 may
require some work and time due to KPI differences but it's doable
if you spend some time.

You don't need to disable skgeinit and sky2. Actually I don't know
where you got the name of skgeinit. AFAIK skgeinit is a function
name of vendor's Linux driver.
