--- Comment #18 from Wallace <incin@incin.me> ---
I am also getting this error:

bnxt0: Using 256 TX descriptors and 256 RX descriptors
bnxt0: Using 0 RX queues 0 TX queues
bnxt0: Using MSI-X interrupts with 1 vectors
bnxt0: iflib_dma_alloc_align: bus_dma_tag_create failed: 22
bnxt0: Unable to allocate device TX queue
bnxt0: Unable to allocate queue memory
device_attach: bnxt0 attach returned 22

This FreeBSD 13.0 server has no issues and is using the BCM57416 card.
Firmware for the network card is 21.85.21.91 and was installed when I got the
server.

bnxt0@pci0:25:0:0:      class=0x020000 rev=0x01 hdr=0x00 vendor=0x14e4
device=0x16d8 subvendor=0x14e4 subdevice=0x4160
    vendor     = 'Broadcom Inc. and subsidiaries'
    device     = 'BCM57416 NetXtreme-E Dual-Media 10G RDMA Ethernet Controller'
    class      = network
    subclass   = ethernet
bnxt1@pci0:25:0:1:      class=0x020000 rev=0x01 hdr=0x00 vendor=0x14e4
device=0x16d8 subvendor=0x14e4 subdevice=0x4160
    vendor     = 'Broadcom Inc. and subsidiaries'
    device     = 'BCM57416 NetXtreme-E Dual-Media 10G RDMA Ethernet Controller'
    class      = network
    subclass   = ethernet


FreeBSD 12.2 server using the BCM57416 card and firmware version 21.65.33.33
works fine. Updated to 21.85.21.92 and I get the 'returned 22 error'. Rolled
the firmware back and things are working again.

bnxt0@pci0:25:0:0:      class=0x020000 rev=0x01 hdr=0x00 vendor=0x14e4
device=0x16d8 subvendor=0x14e4 subdevice=0x4160
    vendor     = 'Broadcom Inc. and subsidiaries'
    device     = 'BCM57416 NetXtreme-E Dual-Media 10G RDMA Ethernet Controller'
    class      = network
    subclass   = ethernet
bnxt1@pci0:25:0:1:      class=0x020000 rev=0x01 hdr=0x00 vendor=0x14e4
device=0x16d8 subvendor=0x14e4 subdevice=0x4160
    vendor     = 'Broadcom Inc. and subsidiaries'
    device     = 'BCM57416 NetXtreme-E Dual-Media 10G RDMA Ethernet Controller'
    class      = network
    subclass   = ethernet

I can upgrade the 12.2 server to 12.3 or 13.0 and keep the firmware on .33 then
upgrade to .92 as a test.
