Subject: [dpdk-dev] [PATCH v2 31/38] common/sfc_efx/base: allow getting VNIC MCDI client handles
Date: Mon, 11 Oct 2021 17:48:50 +0300
Message-ID: <20211011144857.446802-32-andrew.rybchenko@oktetlabs.ru> (raw)
In-Reply-To: <20211011144857.446802-1-andrew.rybchenko@oktetlabs.ru>

From: Viacheslav Galaktionov <viacheslav.galaktionov@oktetlabs.ru>

Equality checks between VNICs should be done by comparing their client
handles. This means that clients should be able to retrieve client handles
for arbitrary functions and themselves.
