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 1d608d2e0d51 Revert "macb: support the two tx descriptors on at91rm9200" 700d566e8171 net: macb: add support for sama7g5 emac interface ec771de654e4 net: macb: add support for sama7g5 gem interface f4de93f03ed8 net: macb: unprepare clocks in case of failure 38493da4e6a8 net: macb: add function to disable all macb clocks daafa1d33cc9 net: macb: add capability to not set the clock rate edac63861db7 net: macb: add userio bits as platform configuration 9e6cad531c9d net: macb: Fix passing zero to 'PTR_ERR' 0012eeb370f8 net: macb: fix NULL dereference due to no pcs_config method e4e143e26ce8 net: macb: add support for high speed interface Thank you, Claudiu Beznea > Andreas. > > -- > Andreas Schwab, sch...@linux-m68k.org > GPG Key fingerprint = 7578 EB47 D4E5 4D69 2510 2552 DF73 E780 A9DA AEC1 > "And now for something completely different." >
