Subject: [Bridge] [PATCH net-next mlxsw v2 14/16] selftests: forwarding: lib: Allow list of IPs for IGMPv3/MLDv2
Date: Wed, 1 Feb 2023 18:28:47 +0100 [thread overview]
Message-ID: <c23017aace3d1c5f7746f0a2a54c7bcb60851c85.1675271084.git.petrm@nvidia.com> (raw)
In-Reply-To: <cover.1675271084.git.petrm@nvidia.com>
The testsuite that checks for mcast_max_groups functionality will need
to generate IGMP and MLD packets with configurable number of (S,G)
addresses. To that end, further extend igmpv3_is_in_get() and
mldv2_is_in_get() to allow a list of IP addresses instead of one
address.
