Subject: next-20250129: rk3399-rock-pi-4b NFS mount and boot failed

The arm64 rk3399-rock-pi-4b boot failed on Linux next-20250129
while mounting rootfs via NFS. Whereas other arm64 devices boot fine.

rk3399-rock-pi-4b:
  boot:
    * gcc-13-lkftconfig

First seen on the the Linux next-20250129..next-20250130
Good: next-20250128
Bad: next-20250129

Theodore Grey bisected this to,
first bad commit:
  [8865d22656b442b8d0fb019e6acb2292b99a9c3c]
  net: stmmac: Specify hardware capability value when FIFO size isn't specified

Anyone have noticed this boot problem on rk3399-rock-pi-4b running the
Linux next-20250129 and next-20250130 kernel.

Boot regression: arm64 rk3399-rock-pi-4b nfs mount and boot failed
