Gigabit Ethernet issue and Android update

Its a known issue with the 3.10.65 BSP kernel. Work is done to correct this problem. For now either use a 100mbit is the quick workaround.

At the end of this very same thread the real state of this issue is outlined: http://forum.pine64.org/showthread.php?t...24#pid9024

1) This is NOT 'a known issue with the 3.10.65 BSP kernel'

2) exactly nobody is 'working' on this since the few people that could solve this are curious whether this problem is related to underpowering situations (keep in mind that it can't be a software issue since most users aren't affected of the reported 'slowness')

3) you should keep in mind that the so called 'bug tracker' over at pine64.pro is a trash can in reality. Everybody can throw in whatever he likes and it will rot there forever (Allowing to list hardware issues as software bugs is somewhat... ahem...)

4) Several users that experience this problem have been asked in the forums to try to verify underpower issues. No one got back to us so far (most probably since they use workarounds now and wait for a 'patch')

5) By recommending workarounds like 'use 100 mbit' you ensure that the issue won't be resolved anytime soon

Great work done to prevent solving problems so far.

tkaiser, those were my exact thoughts after reading this thread: http://forum.pine64.org/showthread.php?t...24#pid9024.

Sounds like no one really knows what the issue is and no one has any dates or timeline on when (or if) it will be fixed. Hopefully the main developers are not the ones on this thread. 

I had high hopes for the Pine64, looks like it may become a paper weight... Back to Pi3.

I think you completely missed tkaiser's point. 

The linux kernels have no issue with speed. Every person I have asked "so what are you hooking the pine to" has yet to answer. Here are some quick iperf numbers from mine this morning.

Code:

At this time there is nothing wrong with the kernels as far as Ethernet. I am not even on the latest I am on  3.10.101-0-pine64-longsleep.

Until someone who has the slowness issue can prove there is an issue with the kernel, we should stop blamint it.  We do have proof that at least for some of us it works fine. If its broken for you, you need to show people, answer detailed questions and be willing to do some homework before anyone can willynilly blame anything. For all we know you have a patch cable with bad noise, a broken wire in it, a dirty connection anything.
