[dpdk-dev] [PATCH 04/10] net/atlantic: macsec hardware structures declaration

[Igor Russkikh <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
