    Subject[PATCH 5.4 073/102] hv_netvsc: flag software created hash value
    Date
    From: Stephen Hemminger <sthemmin@microsoft.com>

    [ Upstream commit df9f540ca74297a84bafacfa197e9347b20beea5 ]

    When the driver needs to create a hash value because it
    was not done at higher level, then the hash should be marked
    as a software not hardware hash.

    Fixes: f72860afa2e3 ("hv_netvsc: Exclude non-TCP port numbers from vRSS hashing")
