    Subject[PATCH 5.2 035/413] net: hns3: fix for FEC configuration
    Date
    [ Upstream commit f438bfe9d4fe2e491505abfbf04d7c506e00d146 ]

    The FEC capbility may be changed with port speed changes. Driver
    needs to read the active FEC mode, and update FEC capability
    when port speed changes.

    Fixes: 7e6ec9148a1d ("net: hns3: add support for FEC encoding control")
