Set the MTU for IB ports in the driver instead of using the firmware default of 2KB (the driver defaults to 4KB). Allow for dynamic mtu configuration through a new, per-port sysfs entry. Since there's a dependency between the port MTU and the max number of HW VLs the port can support, apply a mim/max approach, using a loop that goes down from the highest possible number of VLs to the lowest, using the firmware return status to know whether the requested number of VLs is possible with a given MTU. For now, as with the dynamic link type change / VPI support, the sysfs entry to change the mtu is exposed only when NOT running in SR-IOV mode. To allow changing the MTU for the master in SR-IOV mode, primary-function-initiated FLR (Function Level Reset) needs to be implemented.
