One of the changes to the macb driver between 5.10 and 5.11 has broken
the SiFive HiFive Unleashed. These are the last messages before the
system hangs:

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

Thank you,

In addition, it's worth mentioning that the driver has multiple rx/tx/irq
functions depending on the platforms or chip variants, and that based on
this it should be easy to further reduce this list.
Just my two cents,
