Subject: [dpdk-dev] [PATCH v2 6/8] ipc: fix tap pmd memleak
Date: Tue, 23 Apr 2019 18:43:32 +0100	[thread overview]
Message-ID: <20190423174334.19612-7-herakliusz.lipiec@intel.com> (raw)
Message-ID: <20190423174332.gSpnvNyot-uFW4Qu1D_wCQ2RhI-CrjBOfspZ8mANLdQ@z> (raw)
In-Reply-To: <20190423174334.19612-1-herakliusz.lipiec@intel.com>

When sending synchronous IPC requests, the caller must free the response 
buffer even if the request returned failure. Fix the code to correctly 
use the IPC API.

Bugzilla ID: 228
Fixes: c9aa56edec8e ("net/tap: access primary process queues from secondary")
