Subject: [PATCH] sfc: Store port number in net_device::dev_id

This exposes the port number to userland through sysfs.

Signed-off-by: Ben Hutchings <bhutchings@...arflare.com>

Following on from the earlier discussion of dev_id, here's the necessary
change for sfc.  This depends on commit dd8f61d "sfc: Get port number
from CS_PORT_NUM, not PCI function number".  Please consider including
both of these in net-2.6.

Ben.
