[PATCH] uml: reintroduce pcap support
The pcap support was not working because of some linking problems (expressing the construct in Kbuild was a bit difficult) and because there was no user request. Now that this has come back, here's the support. This has been tested and works on both 32 and 64-bit hosts, even when "cross-"building 32-bit binaries.
