Hello,
I've just installed Server 18.03.3 onto a Macmini2,1 and having terrible wired network performance. Extreme packet loss.
I suspect the NIC driver (sky2) is having timeout issues. This seems to be the normal behaviour of this driver based on Google searches
I unfortunately do not see any failures/errors about the NIC in dmesg or /var/log/syslog
Linux downloadserver 4.15.0-72-generic #81-Ubuntu SMP Tue Nov 26 12:20:02 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
How can I fix this??Code:01:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8053 PCI-E Gigabit Ethernet Controller (rev 22) Subsystem: Marvell Technology Group Ltd.
