scsi: qla2xxx: Add support for setting port speed
This patch adds sysfs node
1. There is a new sysfs node port_speed
2. The possible values are 2(Auto neg), 8, 16, 32
3. A value outside of the above defaults to Auto neg
4. Any update to the setting causes a link toggle
5. This feature is currently only for ISP27xx
