Subject: [dpdk-dev] [PATCH 07/11] net/atlantic: bad logic with offsets talking with firmware
Date: Mon, 29 Apr 2019 08:20:21 +0000	[thread overview]
Message-ID: <64f16386ccec77553d782d82164b3ffc2e5e3b48.1556525874.git.igor.russkikh@aquantia.com> (raw)
Message-ID: <20190429082021.S7gR9QDJHa1dAZa6t-4wTgdJv1Xo62B-I9CNUzZzpoA@z> (raw)
In-Reply-To: <cover.1556525874.git.igor.russkikh@aquantia.com>

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

eeprom write accesses start using non zero configuration memory
accesses. This revealed an issue where firmware interface was actually
always did the uploads starting with zero offset
