Subject: [dpdk-dev] [PATCH 32/38] net/sfc: maintain controller to EFX interface mapping
Date: Fri, 27 Aug 2021 09:57:11 +0300
Message-ID: <20210827065717.1838258-33-andrew.rybchenko@oktetlabs.ru> (raw)
In-Reply-To: <20210827065717.1838258-1-andrew.rybchenko@oktetlabs.ru>

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

Newer hardware may have arbitrarily complex controller configurations,
and for this reason the mapping has been made dynamic: it is represented
with a dynamic array that is indexed by controller numbers and each
element contains an EFX interface number. Since the number of controllers
is expected to be small, this approach should not hurt the performance.
