/**
* Checks that the device has kernel support for the IPv6 ping socket. This allows ping6 to work
* without root privileges. The necessary kernel code is in Linux 3.11 or above, or the
* <code>common/android-3.x</code> kernel trees. If you are not running one of these kernels, the
* functionality can be obtained by cherry-picking the following patches from David Miller's
* <code>net-next</code> tree:
* <ul>
* <li>6d0bfe2 net: ipv6: Add IPv6 support to the ping socket.
* <li>c26d6b4 ping: always initialize ->sin6_scope_id and ->sin6_flowinfo
* <li>fbfe80c net: ipv6: fix wrong ping_v6_sendmsg return value
* <li>a1bdc45 net: ipv6: add missing lock in ping_v6_sendmsg
* <li>cf970c0 ping: prevent NULL pointer dereference on write to msg_name
* </ul>
* or the equivalent backports to the <code>common/android-3.x</code> trees.
