Subject: [PATCH net-next-2.6 8/11] bnx2x: use mask in test_registers() to avoid parity error
Date: Mon, 19 Apr 2010 14:14:37 +0300 [thread overview]
Message-ID: <1271675677.6900.280.camel@lb-tlvb-vladz> (raw)
Properly mask the value to be written to the register (according to the register size) during the self-test.
Otherwise immediate parity error would be generated.
