Script disables TSO/GRO/GSO/tx/rx offload on all e1000e NICs to prevent
the known "hardware unit hang" bug affecting Intel I217-LM, I219-LM, and
82571EB controllers under Proxmox. Applies live + installs systemd
service for persistence.
Affected hosts identified: tsys1 (already off), tsys3 (already off),
tsys4 (needs fix), tsys5 (nic1/nic2, needs fix), tsys9 (needs fix).
tsys6/7 use Broadcom (bnx2/tg3), not affected.
Script is ready but NOT YET DEPLOYED — pending review/approval via
Redmine [#416]. Initial attempt to deploy did not execute properly.
Based on archive/provisioning/Dell/Server/fixeth.sh.

perf-matrix.sh provides on-demand any-to-any performance testing:
- datanet: host-to-host bandwidth matrix over VLAN 1000
- guests: guest-to-guest (k8s/ultix VMs over datanet)
- storage: NFS read/write I/O per host
iperf3 installed on all 7 hosts (systemd service iperf3-server, enabled
but not auto-started) and all production VMs with guest-agent.
Also: tsys3 datanet persistence fix (USB NIC late-enumerate systemd
service), 4 missing reverse DNS zones created, netbird/ultix-mini/
ultix-sidecar/ultix-highside DNS records added (DNS now fully
consistent across all Tailscale nodes). [#413]

Perf testing results (#413):
- Host-to-host datanet: all 7 hosts at ~900-940 Mbps (1Gbps line rate)
- Guest-to-guest: all k8s nodes at ~920-1040 Mbps over VLAN 1000
- Storage I/O: NFS writes 27-65 MB/s (spinning disk), reads cached
Fixed tsys3 datanet: physical NIC enx8cae4ccda774 was DOWN and not
enslaved to the datanet bridge (config was correct but runtime state
was wrong). Enslaved manually, verified connectivity.
Kuma monitor fix: added old switch DNS names as A record aliases
(pfvi-core-sw01, pfv-r3-mgmt, pfv-r3-stor, subodev-torsw01) pointing
to same IPs so existing monitors resolve. Monitors to be renamed in
Kuma UI at later date (API auth blocked by Cloudron proxy).
