----------------------------------------
Bug #2292: re interface with jumbo frames (mtu larger than 1500) hangs after some traffic
http://bugs.dragonflybsd.org/issues/2292
Author: Stefan Krüger
Status: New
Priority: Normal
Assignee:
Category:
Target version:
How to reproduce:
ifconfig re0 mtu 4088
cd /usr; make pkgsrc-create
wait a bit
re0 completely hangs; no ping; nothing when tcpdumping; nothing dmesg either
doing a
ifconfig re0 mtu 1500
gets it back to life though...
Can you try turning off txcsum when using jumbo frame on re0? i.e.
ifconfig re0 -txcsum
Best Regards,
sephe
I did:
ifconfig re0 -txcsum
ifconfig re0 mtu 4088
cd /usr; make pkgsrc-create
still hangs at 26 % (i.e. after transfering about 124.11 MiB)
Please test following patch:

Still hangs :(
- make pkgsrc-create
If problems occur you may have to rm -rf pkgsrc and try again.
mkdir -p /usr/pkgsrc
cd /usr/pkgsrc && git init

I see some packets though when tcpdump'ing -ni re0:

but that's it, no ping, no NFS, no network anymore
