Re: [PATCH V2 net-next 0/2] net: fec: fix TX bandwidth fluctuations

I try below build options, also can't reproduce this issue, so really don't know how to fix it.

make ARCH=arm64 distclean
make ARCH=arm64 allmodconfig
make -j8 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- W=1 / make -j8 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- W=2 / make -j8 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- W=3

I saw many unrelated warnings...

Then it could be sparse. Install sparse and use C=1.
