[dpdk-dev] [PATCH 2/2] net/txgbe: fix link process in KR mode

[Jiawen Wu <jiawenwu@trustnetic.com>]

Set the 'present' parameter to 0 by default. It is configured by hardware,
users can set it to 1 for manual configuration.

Fixes: f611dada1af8 ("net/txgbe: update link setup process of backplane NICs")
