Subject: [PATCH 10/21] net: phylink: support validated pause and autoneg in
|
|
fixed-link
|
|
|
|
In fixed-link setup phylink_parse_fixedlink() unconditionally sets
|
|
Pause, Asym_Pause and Autoneg bits to "supported" bitmap, while MAC may
|
|
not support these.
|
|
|
|
This leads to ethtool reporting:
|
|
|
|
> Supported pause frame use: Symmetric Receive-only
|
|
> Supports auto-negotiation: Yes
|
|
|
|
regardless of what is actually supported.
|
|
|
|
Instead of unconditionally set Pause, Asym_Pause and Autoneg it is
|
|
sensible to set them according to validated "supported" bitmap, i.e. the
|
|
result of phylink_validate().
