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.

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)

Bonding driver form RHEL 7.4 has integrated commit: https://github.com/torvalds/linux/commit/b5bf0f5b16b9c316c34df9f31d4be8729eb86845<https://emea01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Ftorvalds%2Flinux%2Fcommit%2Fb5bf0f5b16b9c316c34df9f31d4be8729eb86845&data=02%7C01%7Cvlad%40mellanox.com%7C446eb3a2e6c049530a2008d569ae4ab4%7Ca652971c7d2e4d9ba6a4d149256f461b%7C0%7C0%7C636531119663401238&sdata=SbYM7B0aSA9LFMrTCCSRu%2BQXt2rjJIJZzFHNZCq9Dk0%3D&reserved=0>
This requires ipoib driver to return correct speed and duplex mode. Commit adding this feature on ipoib driver:
