I see... depending on what services are running on that
network, this might
be some avahi messages or similar stuff; in case this is a
storage-only
network and there is no other stuff floating around, this may
well be the
cause for the issues...

No, I don't think so. Maybe some of the ethernet offloading
stuff in the
NIC is unable to handle larger packets? You may check with
'ethtool -k em1'
what is enabled and may try to selectively disable and retest...
