Re: [PATCH 1/2] stmmac: introduce flag to dynamically disable TX offload for rockchip devices

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.
