Subject: bnx2x: Self-test false positive
X-Git-Tag: MMI-PSA29.97-13-9~32284^2~17
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9dabc4242f7e51d98a71af7ee11a36e637897f9e;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git

bnx2x: Self-test false positive

Self-test false positive
- The memory test should use a mask according to the chip type
- In the register test, check the port only once and not inside the for
  loop (not causing a failure - just ugly)
