Re: [Linux-PowerEdge] Unqualified SFP+ adapter detected

[Michael Watters]

Unfortunately there doesn't appear to be a newer version of the bnx2x
driver available.  I checked on both Dell and QLogic's sites but didn't
have any luck.

We ended up switching the server to use different cables from Dell which
are working fine now.

I've seen this exact complaint from the same card in the same server.
It still works, despite the complaint. One caveat, we're running RHEL6 on
that server.
The cables are Cisco TwinAx copper 10Gb. So far so good.

There are driver and firmware updates for that card on the Dell support
page (look under Qlogic), but I did not have any luck using them.
I'm just running stock RHEL6 and it works.

Does it actually not work, or does it just complain about it?  I know
lots of router/switch vendors will complain, but the optics still
actually work just fine.

I know the Intel ixgbe driver won't actually turn on unsupported SFPs by
default (which is annoying), but there's an option for the module to
turn them on, allow_unsupported_sfp (and then they work fine, including
"ethtool -m" to see DOM info).  I don't know if there's a similar option
for Broadcom.

Sigh, games vendors play with standard ports...

[Linux-PowerEdge] Unqualified SFP+ adapter detected

[Michael Watters]

Hello,

I am setting up a Poweredge R720 server with a Broadcom BCM57810 10 Gbit
NIC however the SFP adapters that we have appear to be incompatible.

> Warning: Unqualified SFP+ module detected, Port 0 from CISCO-TYCO part
number 1-20553783-1

Is there an updated version of the bnx2x driver available for CentOS
7.3?  Would it be possible to update the kernel module to work with
different SFP adapters?  I am willing to patch the kernel source if needed.
