Since the quirk for Ubiquiti U-Fiber Instant SFP module zeroes the support bits and sets 1000baseX_Full only, the above mentioned commit changed the overall computed support from 1000baseX_Full, Autoneg, Pause, Asym_Pause to just 1000baseX_Full. This broke the SFP module for mvneta, which requires Autoneg for 1000baseX since commit c762b7fac1b249a9 ("net: mvneta: deny disabling autoneg for 802.3z modes"). Fix this by setting back the Autoneg, Pause and Asym_Pause bits in the quirk.
