Subject: [PATCH 1/4] jme: lower NAPI weight
Date: Wed, 21 Aug 2013 18:49:28 +0200	[thread overview]
Message-ID: <1377103771-1590-2-git-send-email-mschmidt@redhat.com> (raw)
In-Reply-To: <1377103771-1590-1-git-send-email-mschmidt@redhat.com>

Since commit 82dc3c63 netif_napi_add() produces an error message if
a NAPI poll weight greater than 64 is requested.

jme requests a quarter of the rx ring size as the NAPI weight.
jme's rx ring size is 1 << 9 = 512.

Use the standard NAPI weight.
