Add a linkmode helper to set the flow control advertisement in an
ethtool linkmode mask according to the tx/rx capabilities. This
implementation is moved from phylib, and documented with an
analysis of its shortcomings.

net: add helpers to resolve negotiated flow control2020-02-17T03:39:44+00:00Russell Kingrmk+kernel@armlinux.org.uk2020-02-15T15:49:27+00:00urn:sha1:a87ae8a963bde755b0962bcc18db83d611f63e7a
Add a couple of helpers to resolve negotiated flow control. Two helpers
are provided:
- linkmode_resolve_pause() which takes the link partner and local
advertisements, and decodes whether we should enable TX or RX pause
at the MAC. This is useful outside of phylib, e.g. in phylink.
- phy_get_pause(), which returns the TX/RX enablement status for the
current negotiation results of the PHY.
This allows us to centralise the flow control resolution, rather than
spreading it around.
