Should we also replace all pr_errs with netdev_err in
ql_dump_* functions? I'm not sure how we will use ql_dump_*. For example,
ql_dump_regs is not referred by any kernel source, so I guess it's for
the sole purpose of debugging the driver by the developer. But one
pr_err in ql_dump_routing_entries which is called by dl_dump_regs doesn't
prints out the device name whereas the other does,
