Diagnostic output for Dell Latitude 5520 0A21

At boot, dmesg(8) reports:
pci0: <network, ethernet> at device 31.6 (no driver attached)

pciconf(8) indicates that this laptop has an Intel I219-LM NIC:
none9@pci0:0:31:6:      class=3D0x020000 rev=3D0x20 hdr=3D0x00 vendor=3D0x8=
086
device=3D0x15fb subvendor=3D0x1028 subdevice=3D0x0a21
    vendor     =3D 'Intel Corporation'
    device     =3D 'Ethernet Connection (13) I219-LM'
    class      =3D network
    subclass   =3D ethernet
    cap 01[c8] =3D powerspec 3  supports D0 D3  current D0
    cap 05[d0] =3D MSI supports 1 message, 64 bit=20

dmidecode(8) indicates that the device is disabled, yet according to the BI=
OS
settings it is in fact enabled:
Handle 0x2901, DMI type 41, 11 bytes
Onboard Device
        Reference Designation:=20=20
        Type: Ethernet
        Status: Disabled
        Type Instance: 0
        Bus Address: 0000:00:1f.6

According to Intel, this NIC should be supported by the em(4) driver
<https://www.intel.com/content/www/us/en/products/sku/82185/intel-ethernet-=
connection-i219lm/downloads.html>.
FWIW, the NIC probes, attaches, and operates under Fedora 35 without any
issues.
