If the RBUF logic is not reset when the kernel starts then there may be some data left over from any network boot loader. If the 64-byte packet headers are enabled then this can be fatal. Extend bcmgenet_dma_disable to do perform the reset, but not when called from bcmgenet_resume in order to preserve a wake packet. N.B. This different handling of resume is just based on a hunch - why else wouldn't one reset the RBUF as well as the TBUF? If this isn't the case then it's easy to change the patch to make the RBUF reset unconditional.

[ Upstream commit 0a6380cb4c6b5c1d6dad226ba3130f9090f0ccea ] If the RBUF logic is not reset when the kernel starts then there may be some data left over from any network boot loader. If the 64-byte packet headers are enabled then this can be fatal. Extend bcmgenet_dma_disable to do perform the reset, but not when called from bcmgenet_resume in order to preserve a wake packet.

I was trying to upstream raspberrypi/linux@b65b82f (net: bcmgenet: Reset RBUF on first open) ( context: https://lore.kernel.org/netdev/47ba4ef5a42fe7412d7e3432a0995464@rmail.be/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).
The text was updated successfully, but these errors were encountered:
