If vmnic0 after reboot is disconnected:
cd /tmp
esxcli system maintenanceMode set -e true -t 0
esxcli software acceptance set –level=CommunitySupported
wget http://ftp2.pl.freebsd.org/pub/VM/VMware/Drivers/net-e1000e-2.1.4.x86_64.vib
esxcli software vib install -v /tmp/net-e1000e-2.1.4.x86_64.vib
esxcli system maintenanceMode set -e false -t 0
reboot

Use this for your own risk.
