Subject: [PATCH v2 net-next 5/7] nexthop: Remove redundant group len check in nexthop_create_group().
Date: Wed, 19 Mar 2025 16:06:50 -0700	[thread overview]
Message-ID: <20250319230743.65267-6-kuniyu@amazon.com> (raw)
In-Reply-To: <20250319230743.65267-1-kuniyu@amazon.com>

The number of NHA_GROUP entries is guaranteed to be non-zero in
nh_check_attr_group().

Let's remove the redundant check in nexthop_create_group().
