    Subject[PATCH AUTOSEL 5.4 193/459] netfilter: nft_tunnel: add the missing ERSPAN_VERSION nla_policy
    Date
    From: Xin Long <lucien.xin@gmail.com>

    [ Upstream commit 0705f95c332081036d85f26691e9d3cd7d901c31 ]

    ERSPAN_VERSION is an attribute parsed in kernel side, nla_policy
    type should be added for it, like other attributes.

    Fixes: af308b94a2a4 ("netfilter: nf_tables: add tunnel support")
