Jumbo in the size mix (MTU 9000 + module jumbo pinned), check-first module config trusting GET reads, cable diag async at startup through the reset path, MODULES table dissolved into SETTINGS/LINKS, per-driver NIC counter sets, comment cleanup

AF_PACKET raw sockets everywhere (`sock.go`); flow-director steering; per-packet-MAC-rx-stamped rate buckets (`SO_TIMESTAMPING` cmsg, `rx_filter=ALL` as a hard host check — nics/README.md for what that demands of the NIC; **temporarily bypassed** in `ts.go` so BCM work can run on the X520, which cannot stamp — the check reports yellow and the panel rates read zero there; restore to fatal for the product NIC); read-time-stamped NIC-counter rates; BCM module diagnostics (`phy.go`, over the patched-ixgbe `sff_i2c` debugfs, compound-op framing): bringup identifies both modules, forces EEE off with an AN restart, then runs the ECD — per-pair verdicts, lengths and pair maps are the length/wiring path — and every reset re-runs it, re-baselining the counters only after the diag's own link blip so it is never charged to the run; a 1 Hz poller feeds per-pair SNR margin (vs the ≈26.5 dB operating point; green ≥ 3 dB, amber ≥ 1 dB — provisional until the graded-noise run) and the corrected-error set (PCS 3.33 errored blocks/BER, PMA 1.147 fast-retrain count) to the panel and console; framebuffer UI; harness.
