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:

[   12.468674] libphy: Fixed MDIO Bus: probed
[   12.746518] macb 10090000.ethernet: Registered clk switch 'sifive-gemgxl-mgmt'
[   12.753119] macb 10090000.ethernet: GEM doesn't support hardware ptp.
[   12.760178] libphy: MACB_mii_bus: probed
[   12.881792] MACsec IEEE 802.1AE
