[PATCH net 0/2] bareudp: fix several issues

This patchset is to fix problems when bareudp is used nestedly.

1. If the NETIF_F_LLTX flag is not set, the lockdep warns about
a possible deadlock scenario when bareudp interfaces are used nestedly.
But, like other tunneling interfaces, bareudp doesn't need xmit lock.
So, it sets NETIF_F_LLTTX.
Lockdep no more warns about a possible deadlock scenario.

2. bareudp interface calculates min_headroom when it sends a packet.
When it calculates min_headroom, it uses the size of struct iphdr even
the ipv6 packet is going to be sent.
It would result in a lack of headroom so eventually occurs kernel panic.
