Subject: [dpdk-dev] [PATCH v6 06/22] net/atlantic: add b0 hardware layer
Date: Fri, 12 Oct 2018 11:09:17 +0000	[thread overview]
Message-ID: <a444004b5d9548ffd188ff7dd13f467750bbc76d.1539338074.git.igor.russkikh@aquantia.com> (raw)
In-Reply-To: <cover.1539338074.git.igor.russkikh@aquantia.com>

This is hw_atl logic layer derived from linux atlantic
driver. It contains RX/TX hardware initialization
sequences, various hw configuration.
