	Looking through the source, ~~the driver~~ [https://elixir.bootlin.com/linux/latest/source/drivers/net/ethernet/marvell/sky2.c#L2575 blames the hardware for misbehaving] and generating invalid statuses. More info on this issue in the [https://lkml.kernel.org/netdev/4C6E8545-ADDC-456E-B17B-B3512A6047D1@seehuhn.de/T/ Linux mailing] list.		Looking through the source, there is a note which [https://elixir.bootlin.com/linux/latest/source/drivers/net/ethernet/marvell/sky2.c#L2575 blames the Yukon NIC hardware for misbehaving] and generating invalid statuses. More info on this issue in the [https://lkml.kernel.org/netdev/4C6E8545-ADDC-456E-B17B-B3512A6047D1@seehuhn.de/T/ Linux mailing] list. The hacky code targets the Yukon-2 FE+ network adapter but not the Yukon Optima that this device is using. Perhaps the driver can be patched so this NIC uses the hacky code that circumvents these errors from being reported?

-Searching around showed that around 10 years ago, the <code>sk98lin</code> driver that was provided by Marvell was used. In fact, according to [http://elrepo.org/tiki/DeviceIDs ElRepo's DeviceID page], the PCI device <code>11AB:4381</code> which we have uses <code>kmod-sk98lin</code>. This driver was only available up to EL6 and targeted the 2.6 kernel and was never brought forward (or so I thought). I tried compiling it on the 4.18 kernel but the <code>net_devices</code> struct changed which couldn't be worked around.

 After digging around some more, it looks like this driver was rewritten as <code>sky2</code>. ElRepo has a <code>kmod-sky2</code> package for EL8 at http://elrepo.reloumirrors.net/elrepo/el8/x86_64/RPMS/. After installing this package, and rebooting the machine, the two interfaces came up.
 LAN1 showed up as <code>enp2s0</code> and LAN2 as <code>enp3s0</code>.
