At this point I've settled on snps,txpbl = <0x20> by itself. If I increase the MTU from the default of 1500 I get a stack trace and link reset almost immediately: (https://pastebin.com/raw/5JBtfWei) whether TX Checksumming is ON or OFF.
That said, with the default MTU, I get better speeds when TX Checksumming is on and the PBL tweak is set.
Is there a better option in the horizon for the near future? At least for the Renegade (the only board I have to test) it can serve as a temporary workaround. Should I make a patch to replace force_thresh_dma_mode with txbpl <0x20> for the Renegade specifically?
In any case I would be happy to help as much as I can to figure out if it's a board specific thing, or SoC, or even an issue of the Ethernet device itself.
