1afe36a3c8 Remove WX1820: never had the hardware, evaluation was paper-only

b6e0fe8978 Add NIC datasheets: 82599 rev3.5, 710-series v4.1, E810 full datasheet, ConnectX-5 user manual + mlx5 PRM

9cb82ca3fa Re-transcribe BCM84891L MDIO command and SFP register excerpts in full (all 45 commands, complete serial-ID table); scrub doc-provenance attribution and label all our interjections as field notes

5588ebec6f Resolve X520 open questions on hardware: ETQF raw-L2 steering and single-hold compound I2C proven; 82599 has no all-packet exact-timestamp path so it is disqualified as product NIC (diagnostics-only), counter route rejected for a cable tester

910379e614 Correct Wiitek danger analysis: whole 3.0x8000+/31.0xF000+ window is lethal, not just *.??64 -- 88Q2220 recipe is IN the danger zone; record live baseline and no-safe-VCT-path finding

ad9bc9fae4 BCM ECD recovered from OpenBCM SDK and proven: 1E.4006 start, 1.A896 verdicts, 1.A897-9A per-pair meters -- meter-accurate on a 45m cable, healthy pairs report length

c57816345f Restructure docs: per-device directories under modules/ and nics/ with co-located datasheets, state centralized in state.md, prose tightened into lists and tables

dc1fa6538d Record FS probe sweep: AutogrEEEn found and forced off (defensive at bringup), identity pair map, FR count as metric, firmware DATA1 reliability caveat

ff64b59fe0 Transcribe BCM PDFs to markdown visually (tables intact); catalog probe candidates: EEE advertised in reference bringup, EMI cmds are fast-retrain enables, 1588/loopback/ECD chapters missing

4023d7ccf0 Add FS/BCM capability inventory; drop SNR/power-backoff length proxies -- length is PHY features or NIC timestamps only

01e00dfffe BCM path proven on X520: fix multi-byte i2c read (SDA release), GET_SNR is 0x8030 invoked bare, IEEE SNR regs dead on BCM, module pause forced off

6f787c0873 Record X520 install: FS+Wiitek seated and linked, FS's honest EEPROM is what trips ixgbe qualification, uplink moved to enp88s0

5f4a8ceb57 Vendor AQR datasheet, correct timestamp model (hw rx stamps are a hard requirement), order ConnectX-5, map 82599 bucket-timestamp routes

73074040e0 Answer open questions from desk analysis: ETQF steering, E820 is post-FEC, compound I2C op, forced co-location

8c8e0c7d32 Add open-questions doc for pre-hardware deep-dive

44e010caa9 Note Wiitek ixgbe RollBall client and flag ixgbe RX-steering as open investigation

3f1bb03e52 Record X520 ixgbe raw-i2c patch and BCM client prep in state doc

6597a11c33 Add in-repo project docs: goals, state, hardware, module-PHY transports, module diagnostics, and measurement lessons

6d73221123 Hold a fatal error on the framebuffer and reboot in five minutes rather than exiting, since init's death drops the kernel's panic screen over the cause
cd259556d4 Build i40e into the appliance kernel, whose forbidden list predated the noise pair that needs it
