Allow to read the carrier status of a netdevsim device via ethtool, like most of Ethernet devices allow.
Also, allow to set its carrier status via sysfs. Currently it's only possible by linking a peer device and setting its admin state to UP/DOWN. By editing the carrier status via sysfs tests that need to check carrier related stuff may be simpler. The third patch add the proper selftest for both things, and the fourth and fifth fix a few small bugs in the selftest itself.
