Hi,
I'm trying Lede HEAD with a BananaPI (SUNXI7 A20) and have an
issue
with the network connection:

Does anybody have a clue why this happens ?
Can you please post a full dmesg.
yes, of course:

I don't have packet loss but I have slow upload (A20 Olimex Lime2)
but
maybe is the uboot bug found on the internet if is not already in
the
uboot mainline, if I increase the number of parallel connection the
speed goes up to 200Mb/s

Hi,
I think the U-Boot should not influence this.
@Gred could you please remove all the patches from
target/linux/sunxi/patches-4.9/ and test with such an image and then
report back your results please? It could be that something when
wrong
when I backported some clock patches.
Hauke
Hi Gerd,
Could you please also test in addition my sunxi feature branch here:
https://git.lede-project.org/?p=lede/hauke/staging.git;a=shortlog;h=refs/heads/sunxi
It contains an updated version of the stmmac driver, I did this
mostly
to add support for the A64, but it could also fix your problems.
Hauke
thanks for your assistance.
I've tested both versions, stock Lede HEAD without patches and your
git.
Both showing the same problem with packet lost and poor upload
bandwidth.
Regards
Gerd
Ok they I can probably not help any more, this looks more like a bug in
the upstream kernel introduced between kernel 4.4 and 4.9. It probably
makes sense to talk directly to the Linux stmmac maintainers about this
problem.
Hauke
IMHO Cristian mentioned it already, there seems to some magic in the old
Uboot versions aka CONFIG_GMAC_TX_DELAY.
I adapted
https://groups.google.com/forum/#!msg/linux-sunxi/Y_Zh5juEJG4/egjJojeTgS8J
and received much better results:

I'm not an Uboot expert, maybe somebody else could migrate
this parameter from the old Uboot to the new one.
