USB nix axen not working reliable

Synopsis:  USB nic axen not working reliable
Category:  kernel
Environment:
System  : OpenBSD 5.6
Details : OpenBSD 5.6-current (GENERIC.MP) #607: Mon Nov 24 
14:23:38 MST 2014
 
dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP

Architecture: OpenBSD.amd64
Machine : amd64
Description:
My USB3 Edimax Gigabit Ethernet adapter (axen) does not work reliable
anymore.

When plugged in into the USB 2 port ifconfig shows status: active
for a few seconds. Then it changes to status: no carrier while still
connected and does not changes its status anymore. If dhclient configures 
axen0 during the first few seconds it stays active and works fine. 

When connected to the USB 3 port it also shows status: active for the
first few seconds. If it then gets configured with dhclient it either
freezes the hole system or fills dmesg with checksum err and does not
work. Somethimes the system panics instead.

o The details when attached to the USB 2 port:

Xconsole quickly filled with the message below and the pc did not react
anymore.

dmesg is then full of the following, network does not work anymore:

yacc buffer overflow

2014-11-29 Thread Andrey Skvortsov 
Hello.

I'v faced with yacc segmentation fault error while trying to build
TkGate-2.0b10 from tkgate.org
(http://www.tkgate.org/downloads/tkgate-2.0-b10.tgz) on OpenBSD-5.6. Error
appears when yacc parses ./src/tkgate/vgrammar.y file (attached).
I have no any tests and knowledge about yacc structure, but the attached
patch seems to fix the problem in this particular case at least.

Yours sincerely,
Andrey V. Skvortsov
