Still getting this issue on this version 9.3.

This issue has been present since 9.1, when there will be a fix?

Probably never, if you don't provide the necessary information:
- Exact chip type
- PCI PnP ID (ven & dev), output of "lspci -vn" for NIC
- Output of "ethtool -k ethX"

IMO Intel is to blame here for producing such bad hardware - so many errata in so many different chips.
I'll not discuss this, but it seems this is happening on linux systems, I've never seen this problem on windows machines, in fact this same board I use on UTM also use another one on windows 7 and never had problems.
BTW: The second adapter in your lspci output appears to be a different one: Intel 82574L, which is already addressed by Sophos via /etc/udev/rules.d/20-nic.rules.
BTW I doubt Sophos monitores this Beta subforum anymore since 9.300 is released, so I think the workaround posted above won't make it into next release (if ever). I think you need to create a support ticket.
