I can successfully get it set up using DHCP, but when I start using it, I get error messages such as: "mskc0: Tx descriptor error" and "msk0: watchdog timeout".

Some users have no problems but others seem to suffer from the issue. There is also a PR about this but it seems it's hard to fix that mainly because I don't have access to the hardware. > mskc0: [MPSAFE] > mskc0: [FILTER] > pci5: driver added > pci6: driver added > msk0: link state changed to DOWN > msk0: link state changed to UP > mskc0: Tx descriptor error > mskc0: Tx descriptor error > mskc0: Tx descriptor error > mskc0: Tx descriptor error > mskc0: Tx descriptor error > mskc0: Tx descriptor error > mskc0: Tx descriptor error > mskc0: Tx descriptor error > mskc0: Tx descriptor error > mskc0: Tx descriptor error > msk0: watchdog timeout > msk0: link state changed to DOWN > msk0: link state changed to UP
