Subject: [PATCH 4.14 19/33] net: phylink: Fix flow control for fixed-link
Date: Thu,  8 Aug 2019 21:05:26 +0200	[thread overview]

[ Upstream commit 8aace4f3eba2a3ceb431e18683ea0e1ecbade5cd ]

In phylink_parse_fixedlink() the pl->link_config.advertising bits are AND
with pl->supported, pl->supported is zeroed and only the speed/duplex
modes and MII bits are set.
So pl->link_config.advertising always loses the flow control/pause bits.

By setting Pause and Asym_Pause bits in pl->supported, the flow control
work again when devicetree "pause" is set in fixes-link node and the MAC
advertise that is supports pause.

Results with this patch.

Legend:
- DT = 'Pause' is set in the fixed-link in devicetree.
- validate() = ‘Yes’ means phylink_set(mask, Pause) is set in the
  validate().
- flow = results reported my link is Up line.

+-----+------------+-------+
| DT  | validate() | flow  |
+-----+------------+-------+
| Yes | Yes        | rx/tx |
| No  | Yes        | off   |
| Yes | No         | off   |
+-----+------------+-------+
