Subject: [dpdk-dev] [PATCH v2 1/7] net/atlantic: macsec hardware structures declaration
Date: Wed, 17 Apr 2019 15:45:28 +0000	[thread overview]
Message-ID: <85a9511657c50db1d9767bcd73022f7092cad0a5.1555515863.git.igor.russkikh@aquantia.com> (raw)
In-Reply-To: <cover.1555515863.git.igor.russkikh@aquantia.com>

From: Pavel Belous <pavel.belous@aquantia.com>

Here we define hardware and software configuration structures
for macsec interface. MACSEC itself is implemented in Phy module,
but its configuration is done via firmware interface
