This series addresses link-related issues on Wangxun Amber-lite 25G/40G NICs
(CR/KR training, hot-plug, 10G link state).
---
v11:
- P12: fall back to the default value when an FFE tap does not fit the
register field, instead of only logging it.
- P13: change the patch from a new feature to a fix:
take the transmitter down on AML40 link down. Clearing GPIO bit 1,
which holds the module in reset, does not stop the transmitter for
every DAC cable and QSFP module. The laser_off devarg and its
documentation are dropped; link setup runs again on link-up to
restore what link-down disabled.
- P17: fix warnings in check-git-log, and add the Cc: stable tag that
belongs with the Fixes line.
---
v10:
- P12: check the FFE taps against the register field width of the MAC in
use, instead of only for the 40G one. On the Sapphire the main and
pre taps are six-bit fields and the post tap is seven-bit, so a
larger value spills into the neighbouring field rather than being
truncated.
- P12/P13: say "Amber-Lite 40G NIC" for bp_capa and laser_off, the only
MAC that implements either.
- P17: add a new patch to rename fiber_suppport_speed to fiber_support_speed.
The field was added with the misspelling in 234ce0d1fa, copied from the
out-of-tree base driver.
---
v9:
- P02: build autoneg_advertised from one mask instead of three ifs, and
drop the out-of-tree reference from the message.
- P03: fix the same wrong RXS field in txgbe_e56_cfg_10g(), and add the
Fixes tag for the 25G commit that introduced that copy.
- P10: report module removal and cancel the AN73 watchdog only on the
transition to not-present, so an empty cage no longer repeats both
on every poll.
- P12: reset invalid bp_capa values to 0, log AML40 ffe_* values above
0xFF before their low bytes are replicated across the four lanes,
and document the applicable FFE value range.
- P13: clarify that laser_off disables the E56 PHY PMD through PMD_CFG0
for DAC cables, while QSFP modules use the SFF-8636 Tx-disable byte.
- P15: rewrite the unknown-module comment, drop the debug print that ran
on every watchdog tick, and drop a commit-message bullet for a branch
that is not in the parent tree.
- P16: clear TXGBE_FLAG_NEED_LINK_CONFIG before the administrative-down
early return, so a 25G SFP port can recover after set_link_down() and
set_link_up().
