Subject: net/bnxt: fix reporting of link status
X-Git-Tag: spdx-start~3035
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=bc8ee8572e8e5f82e4cd695c107f3fbcc42a5674;p=dpdk.git

net/bnxt: fix reporting of link status

This patch fixes incorrect reporting of link status

1) When link is down, set speed to zero. Otherwise a wrong non-zero
   speed will be displayed.

2) DAC cables can detect there is a signal, but it necessarily does not
   mean link is up. Code previously treated this as link up.
