Subject: [PATCH net-next] korina: periodically poll the media
Date: Thu, 28 May 2009 12:58:41 +0200 [thread overview]
Message-ID: <200905281258.41956.florian@openwrt.org> (raw)
This patch makes the korina driver poll the media
for link change. This is actually required on
Mikrotik RB532 (not RB532A) for korina to
operate properly.
