[Users] kernel: scsi host8: ib_srp: SRP_LOGIN_REJ: requested max_it_iu_len too large

[Tom Robinson]

Hi,

I hope this is the right list to ask this question. Please let me know if
otherwise.

We are trying to configure the following cards on Arch Linux. This is part
of a reconfiguration of our infrastructure and change of OS from CentOS to
Arch. These cards were working well under CentOS 7 but I can't seem to get
them to work under Arch Linux.

05:00.0 InfiniBand: Mellanox Technologies MT25408A0-FCC-QI ConnectX, Dual
Port 40Gb/s InfiniBand / 10GigE Adapter IC with PCIe 2.0 x8 5.0GT/s In...
(rev b0)

(rev b0)

Currently I am getting the following error on startup of the srp_daemon:

kernel: scsi host8: ib_srp: SRP_LOGIN_REJ: requested max_it_iu_len too large

Has anyone seen this before? I have done a lot of searching on the internet
but as yet have not come across a solution. Can someone please help and
shed some light on this?

More complete/contextual logging is below:
