disable genet receiver when disabling dma in firmware instead of linux genet reset

[alien999999999]

I was trying to upstream https://github.com/raspberrypi/linux/commit/b65b82fbd2ce90c3e96cb10e1e21a784a60b6a9a (net: bcmgenet: Reset RBUF on first open) ( context: https://lore.kernel.org/netdev/[email protected]/T/ ):

And there was discussion of that it would be better to fix this in firmware, rather than try to make the workaround in kernel.

The suggestion is that likely DMA disable is not enough, and receiver reset is necessary too.

Would it be possible to try to get this fix in the firmware? I can easily test a firmware build of this (without the reset patch).
