Subject: [PATCHv2 net 5/6] cxgb4: Avoid dumping Write-only registers in register dump
Date: Mon, 1 Sep 2014 19:54:59 +0530 [thread overview]
Message-ID: <1409581500-11264-6-git-send-email-hariprasad@chelsio.com> (raw)
In-Reply-To: <1409581500-11264-1-git-send-email-hariprasad@chelsio.com>
Avoid dumping MPS_RPLC_MAP_CTL for reg dumps; this is a Write-Only register.
Reading this register may cause MPS TCAM corruption.
