Hi Arlin,

Sorry for the delay, had some logistic stuff to work out.

Hope this is sufficient:
Vlad,

Please pull following fix:
https://github.com/mkalderon/ofed-compat-rdma/commit/01d945c12286b1ad8960ffa74b64fcd256c873e7

Let me know if you prefer I email a patch
I updated the Bug but left it assigned to me -> not sure who I’m supposed to assign it to at this point?

Thanks,
Michal

Michal and Pradeep,

OFA Interop Working Group is anxiously waiting for RC1 for Interop testing (scheduled to start this week).
Is it possible to get Vlad some patches soon so we can move to RC1 by end of the week?

Thanks,
Arlin

True, thanks for catching this. Please open a qedr bug so we can track as critical/blocking.

Tatyana and Pradeep, do Intel and/or Broadcom drivers need similar changes?

Anyone else?

We assumed this is a generic issue since it happened on several adapters, I see now with the bug resolve that Steve made changes specific to cxgb3
We need to make similar changes in qede.

Thanks,
Michal

Hi

We’re seeing an issue on SLES12SP3 with modifying mtu.

linux-p4eo:~ # ifconfig eth7 mtu 9000

SIOCSIFMTU: Invalid argument

Dmesg: eth7: Invalid MTU 9000 requested, hw max 1500

We’ve seen this with other vendor devices as well.
Chelsio reported an issue in the past regarding MTU change,
But I didn’t see any related bugs open or discussions.

Has this been discussed since?
Attaching relevant email

Thanks,
Michal

>>2. New bugs:  True Scale qib bonding issue on RH 7.4, SLES 12.1 and 12.2 – Need update from Bill Schmidt (Intel)

Bug 2664<http://bugs.openfabrics.org/show_bug.cgi?id=2664> - Bonding doesn't work on RHEL 7.4

Bonding driver form RHEL 7.4 has integrated commit: https://github.com/torvalds/linux/commit/b5bf0f5b16b9c316c34df9f31d4be8729eb86845

This requires ipoib driver to return correct speed and duplex mode.  Commit adding this feature on ipoib driver:

https://github.com/torvalds/linux/commit/0d7e2d2166f6b0b7d1959ca858052a15feb574cc was added in 4.12 kernel, so it is missing from OFED 4.8 compat-rdma.

In consequence Bonding driver cannot retrieve required data and fails.

Bug 2665<http://bugs.openfabrics.org/show_bug.cgi?id=2665> - Bonding causes kernel panic on SLES 12.1 and SLES 12.2

Bonding driver from SLES 12.1/12.2 is missing kernel panic fix commit: https://github.com/torvalds/linux/commit/1533e77315220dc1d5ec3bd6d9fe32e2aa0a74c0

added in linux kernel 4.8. This makes it incompatible with ipoib drivers from OFED 4.8 compat-rdma.

•Chelsio validation team hits bug, engineering team cannot reproduce.
•Steve (Chelsio) needs help from Tatyana’s (Intel) team to reproduce and isolate.

2. New bugs:  True Scale qib bonding issue on RH 7.4, SLES 12.1 and 12.2 – Need update from Bill Schmidt (Intel)

•         OFED 4.8-2 RC1 schedule: (2 blocking bugs)
