Pull networking fixes from David Miller:
 "Last bit of straggler fixes...

  1) Fix btf library licensing to LGPL, from Martin KaFai lau.

  2) Fix error handling in bpf sockmap code, from Daniel Borkmann.

  3) XDP cpumap teardown handling wrt. execution contexts, from Jesper
     Dangaard Brouer.

  4) Fix loss of runtime PM on failed vlan add/del, from Ivan
     Khoronzhuk.

  5) xen-netfront caches skb_shinfo(skb) across a __pskb_pull_tail()
     call, which potentially changes the skb's data buffer, and thus
     skb_shinfo(). Fix from Juergen Gross"
