[PATCH v6 00/15] Wangxun fixes and new features

[Zaiyu Wang <zaiyuwang@trustnetic.com>]

This series addresses link-related issues on Wangxun Amber-lite 25G/40G NICs
(CR/KR training, hot-plug, 10G link state).

---
v6:
 - fix the apply failure.
---
v5:
 - drop the UDP tunnel patch: the generic UDP tunnel flag covers any UDP
   tunnel, so the tunnel type cannot be resolved from the destination port.
 - P02: advertise 10G, 25G, and 40G from the requested speed mask instead
        of the device ID, so the 25G and 40G parts advertise 10G by
        default as well.
 - P07: keep the patch limited to decoding the 10G link speed from PORTSTAT;
        the AML40 default 10G|40G advertisement change is now in P02.
 - P09: gate the SFP detection alarm and the AN73 watchdog on a new per-port
        flag that dev_stop clears before the first cancel.
        cancel SFP detection before the watchdog.
 - P10: re-arm the 40G module poll only while the SFP/AN73 alarm flag is set.
 - P12: treat the ffe_pre2 and bp_capa devargs as a feature rather than a fix;
        drop the Fixes tags and stable Cc, and document the 25G/40G Amber-Lite
        FFE defaults.
 - P14: bound the AN page exchange, propagate its timeout to the watchdog h
        andler, and avoid register reads used only by disabled BP debug logs.
 - P15: stop clearing the auto_neg devarg when a 10G-only DAC disables AN;
        derive the effective AN73 state from the current module capabilities
        instead. Classify 40G active cables through the optical path, unify
        DAC checks on txgbe_is_dac_cable().

Not handled in this revision:

 - P12: bp_capa is not range-checked. Devarg validation will be added in a
        separate change so all txgbe devargs can be handled consistently.
 - P14: the AN page exchange still busy-waits on the alarm thread and can
        delay handling for other ports. A later change will decouple negotiation
        from the alarm callback and run per-port negotiations in parallel.
