Subject: [PATCH 9/9] net: davinci_emac: extended register dumps on tx timeout
Date: Mon, 13 Sep 2010 14:07:31 -0400 [thread overview]
Message-ID: <1284401251-8846-10-git-send-email-cyril@ti.com> (raw)
In-Reply-To: <1284401251-8846-1-git-send-email-cyril@ti.com>
This patch hooks up the emac_dump_regs() function to use cpdma dump routines.
Further, we dump registers on transmit timeout, to make such timeouts
debuggable.
