I haven't but I am currently trying to hunt down a (probably unrelated) Ethernet issue on an older Meson8m2 SoC currently. All Amlogic Meson SoCs use a DWMAC IP for Ethernet connectivity plus there's a little bit of "glue" IP for the xMII connecting to the SoC's IO pads I think it's a good idea to involve the netdev and (probably even more important) stmmac maintainers. Anything skb related is handled by the stmmac driver. So I am hoping that someone with expertise in that area can give any hints for debugging or reproducing this.

I haven't but I am currently trying to hunt down a (probably unrelated) Ethernet issue on an older Meson8m2 SoC currently. All Amlogic Meson SoCs use a DWMAC IP for Ethernet connectivity plus there's a little bit of "glue" IP for the xMII connecting to the SoC's IO pads I think it's a good idea to involve the netdev and (probably even more important) stmmac maintainers. Anything skb related is handled by the stmmac driver. So I am hoping that someone with expertise in that area can give any hints for debugging or reproducing this.
