[dpdk-dev] [PATCH 3/3] net/bnxt: fix incorrect reporting of link status

[Ajit Khaparde]

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 perviously treated this as link up.
