           Summary: BCM57414 not initializing
           Product: Base System
           Version: 12.1-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Many People
          Priority: ---
         Component: kern

Hello,

I am using the following system:

540-BCKU : Broadcom 57414 Dual-Port 25GbE SFP28 LOM Mezz Card
405-AAMS : PERC H740P RAID Controller, 8G B NV Cache, Mini card
400-BDSS : 240GB SSD SATA Mixed Use 6Gbps 512e 2.5in Hot-Plug S4610 Dri ve
400-AVEZ : 2.4TB 10K RPM SAS 12Gbps 512e 2.5in Hot-plug Hard Drive
384-BCJD : PowerEdge R7515 Motherboard, with 2 x 1Gb Onboard LOM (BCM57 20)
379-BDSS : SAS/SATA Backplane
370-AEVR : 3200MT/s RDIMMs
370-AEVQ : 16GB RDIMM, 3200MT/s, Dual Ran k
338-BSWO : AMD 7302P 3GHz,16C/32T,128M,15 5W,3200
321-BERX : 2.5" Chassis with up to 24 Hot Plug Hard Drives
210-ASVQ : PowerEdge R7515 Server

The network adapter at the top is non-functional in the 12.1 release.

I am able to check for the Broadcom 57414 drivers via:
>>kldstat | grep if_bnxt

It returns the memory space loaded and then also shows it is functional.

If I try to see the device or bring it online it does not show nor work:
>>ifconfig does not show bnxt0 or bnxt1
>>ifconfig bnxt0 up does not enable or show the device

If I use

lspci | grep NetX it does show the PCI device as being loaded and lists details
within pciconf if I map it to the device ID of pci02:00:0

But if I force unload the if_bnxt and then reload:
>>kldunload if_bnxt
>>kldload /boot/kernel/if_bnxt.ko

It states it fails due to " bus_dma_tag_create failed return: 22"

Am I doing something wrong or?
