Subject[PATCH 5.5 136/170] netfilter: flowtable: populate addr_type mask
Date
From: Edward Cree <ecree@solarflare.com>

commit 15ff197237e76c4dab06b7b518afaa4ebb1c43e0 upstream.

nf_flow_rule_match() sets control.addr_type in key, so needs to also set
the corresponding mask. An exact match is wanted, so mask is all ones.

Fixes: c29f74e0df7a ("netfilter: nf_flow_table: hardware offload support")
