Great explain ... 2 questions: 1 - BCM57810 is gen2 ( I never see any gen3 57810 ) in 10Gbase-t or sfp+ QLE3442 is gen3 Will thuis crossflash activate gen3 in BCM57810 ? 2 - I already used BCM578109 and QLE3442 ( sfp+ ) with great results in 2.5Gb/s with a DFP-34X-3C3 xpon . Using a...

Try Solarflare SFN7122F. It's dual port gen3 x4. If one port is enough x2 must work. Just 5.9W of power consumption.. https://www.ebay.com/itm/125196769193 Another option is based on BCM57840 pcie gen3 x4 but using much more power ( like 10W ). Stable with good support ...

Another config to look ... If you insert a nic in a slot with enumerate lower than the nic already installed the name of thje interfaces can change. Example: I have an 10Gb AQC107 NIC that the system enumerate as en50s0f0. If I insert another card in a pcie, tthe AQC107 changes to enp51s0f0 ...

Some hints to verify ... The Connectx3 MCX354A-FCBT 40gig VPI must be in ethernet mode, not in infiniband mode. Cards in Infiniband mode doesn't show in ifconfig.You need infiniband-diags ( ibstawt , ibstatus ) qsfp ok ->...

Any change log about the recent versions }?

No. DAC = direct attach cable ( passive ) AOC =[ Active optical cable ( active ) The SFP+ to RJ45 is "Active" but using a copper interface instead of optical. The SFP+ to RJ45 is more like the AOC cable.

I used mlxconfig to reset the configs after an upgrade in an very old card. Half of the settings are missing.

Looking at the query: - The card have 2 ports and is a Connectx-3 NON pro. Doesn't have any vpi references in settings and GUIDs are invalid. - even being a connectx-3 non pro, the configs looks missing some keys from the last versions. I sugest you to reset the configs using mlxconfig...

As a workwaround... try using ethtool to force a test in the port. This will disable and re enable the link during the test. ethtool -t /dev/enp40s0f0

RTL8373 based L2 switch. Interface is chinese or english. Webdesign is poor but works.

I used type B cable with this transceiver. https://www.ebay.com/itm/115505386250 with " 3M MPO Cable 12 Fiber OM3 Type B MPO-MPO Famale Multimode 3mm Fiber Patch Cord " ...

I bought one card and is exactly what I guess. 4x RTL8125b and 1 asmedia pcie bridge chip. 33:00.0 PCI bridge: ASMedia Technology Inc. Device 1806 (rev 01) 34:00.0 PCI bridge: ASMedia Technology Inc. Device 1806 (rev 01) 34:02.0 PCI bridge: ASMedia Technology Inc. Device 1806 (rev 01) 34:06.0...

Melanox driver doesn't support changing parameters by sysfs. The params must be declared at loading module.

One extra caution is the pcie gen and availability of lanes. Examples 533FLR-T is pcie 2.0 x8 ( needs all to full bandwidth of both ports ) 556FLR-SFP is pcie 3.0 x8 ( works perfectly using pcie 3.0 x4 ) 544+FLR-QSFP is pcie 3.0 x8 ( 80Gb/s using both ports limited by 63Gb/s of bandwidth at pcie...

I have a lot of these flexlom cards installed with adapters in pcie slots. The only concern is air flow to keep the card cool/warm. HP 331FLR ( BCM5719 ) 4x1Gb/s baseT 533FLR-T ( BCM57810 ) 2x10Gb/s baseT 530FLR-SFP ( BCM57810 ) 2x10Gb/s SFP+ 556FLR-SFP ( Emulex XE-102 ) 2x10Gb/s SFP+ 561FLR-T...
