Subject: [dpdk-dev] [PATCH 1/4] net/ixgbe: fix warning with GCC 9 on Fedora 30
Date: Wed, 1 May 2019 20:50:11 +0100 [thread overview]
Message-ID: <20190501195014.2938-2-bruce.richardson@intel.com> (raw)
Message-ID: <20190501195011.UZPPPg4ZALhKdh8ja_zVRQmIG9JNgc4O26s7DNSD6QI@z> (raw)
In-Reply-To: <20190501195014.2938-1-bruce.richardson@intel.com>
Compiling on Fedora 30, we get the following warning, causing build failure
when Werror flag is set:
../drivers/net/ixgbe/ixgbe_rxtx.c:2141:14: warning: ‘nmb’ may be used uninitialized in this function [-Wmaybe-uninitialized]
2141 | rxe->mbuf = nmb;
| ~~~~~~~~~~^~~~~
Initializing the value to "NULL" fixes the issue.
Fixes: 8eecb3295aed ("ixgbe: add LRO support")
