Subject: [dpdk-dev] [PATCH 2/4] bnxt_alloc_vnic_attributes: ensure entry_length is unsigned
Date: Wed, 28 Sep 2016 15:20:02 -0400 [thread overview]
Message-ID: <1475090404-20707-3-git-send-email-linville@tuxdriver.com> (raw)
In-Reply-To: <1475090404-20707-1-git-send-email-linville@tuxdriver.com>
Otherwise, the inherent cast when multiplying entry_length by max_vnics
in the call to rte_memzone_reserve could promote max_vnics to a signed
value, causing hilarity to ensue...
