Subject: [PATCH 05/14] MIPS: OCTEON: configure minimum PKO packet sizes on CN68XX
Date: Thu, 13 Aug 2015 16:21:37 +0300	[thread overview]
Message-ID: <1439472106-7750-6-git-send-email-aaro.koskinen@nokia.com> (raw)
In-Reply-To: <1439472106-7750-1-git-send-email-aaro.koskinen@nokia.com>

From: Janne Huttunen <janne.huttunen@nokia.com>

CN68XX has common minimum packet size filters that need to be configured
for the traffic to work. Just set them to a default value.
