====================
net, net/mlx4: Add sysfs file for port number

Modern distro's are using biosdevname to rename interface to a name based on
slot/port number.
biosdevname can't get the port number of devices that have multiple ports that
share the same PCI function.
This patch adds a sysfs file under: /sys/devices/.../net/<interface>/dev_port,
that contains the port number (0 based) - to be used by biosdevname.
Also, dev_id was wrongly used in mlx4_en driver - added a patch that fix it.

This patch was tested and applied over commit 51adfcc "net: bcmgenet: remove
unused bh_lock member"
