Subject: [PATCH 4.19 018/142] net: phy: sfp: correct store of detected link modes

4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Baruch Siach <baruch@...s.co.il>

[ Upstream commit d7f7e0018b96fd1a30a968faa9464eb57372c1ec ]

The link modes that sfp_parse_support() detects are stored in the
'modes' bitmap. There is no reason to make an exception for 1000Base-PX
or 1000Base-BX10.

Fixes: 03145864bd0f ("sfp: support 1G BiDi (eg, FiberStore SFP-GE-BX) modules")
