I don't have a SiFive HiFive Unleashed to investigate this. Can you check
if reverting commits on macb driver b/w 5.10 and 5.11 solves your issues:

git log --oneline v5.10..v5.11 -- drivers/net/ethernet/cadence/
1d0d561ad1d7 net: macb: Correct usage of MACB_CAPS_CLK_HW_CHG flag

Unfortunately, that didn't help.

Sorry, for being late to test this, but I just compiled and booted
5.11.6 and ethernet works just fine for me:

As you can see I haven't updated OpenSBI or u-boot in a while, don't
know if that makes a difference. You can fetch the config is used
here:
