Marek BehúnandGreg Kroah-Hartman c0aa43f9c3 net: sfp: Fix quirk for Ubiquiti U-Fiber Instant SFP module
commit adcbadfd8e upstream.

Commit fd580c9830 ("net: sfp: augment SFP parsing with
phy_interface_t bitmap") did not add augumentation for the interface
bitmap in the quirk for Ubiquiti U-Fiber Instant.

The subsequent commit f81fa96d8a ("net: phylink: use
phy_interface_t bitmaps for optical modules") then changed phylink code
for selection of SFP interface: instead of using link mode bitmap, the
interface bitmap is used, and the fastest interface mode supported by
both SFP module and MAC is chosen.

Since the interface bitmap contains also modes faster than 1000base-x,
this caused a regression wherein this module stopped working
out-of-the-box.

Fix this.
