Subject: [PATCH 13/21] net: phylink: fix ksettings_set() ethtool call
|
|
|
|
While testing a Fiberstore SFP-10G-T module (which uses 10GBASE-R with
|
|
rate adaption) in a Clearfog platform (which can't do that) it was
|
|
found that the PHYs advertisement was not limited according to the
|
|
hosts capabilities when using ethtool to change it.
|
|
|
|
Fix this by ensuring that we mask the advertisement with the computed
|
|
support mask as the very first thing we do.
|
|
|
|
Fixes: cbc1bb1e4689 ("net: phylink: simplify phy case for ksettings_set method")
