Subject: [PATCH v2 1/4] common/multipath-over-rdma: Fix expand_ipv6_addr()
Date: Fri, 13 Dec 2019 09:32:29 -0500	[thread overview]
Message-ID: <20191213143232.29899-2-bvanassche@acm.org> (raw)
In-Reply-To: <20191213143232.29899-1-bvanassche@acm.org>

For IPv6 address ::1, instead of returning
0:0000:0000:0000:0000:0000:0000:0000:0001, return
0000:0000:0000:0000:0000:0000:0000:0001.
