- Added check that the SCOPE ID is only restored for IPv6 linklocal
addresses.
- Changes made by r237263 in the "cma_bind_addr()" function did not
check if the socket address was of type IPv6 and used the IPv4
socket address for IPv6 addresses. This caused the function to
fail. Fixed this.
- In the "rdma_gid2ip()" function and some other places the "sin6_len"
and "sin6_scope_id" fields were not set for IPv6 socket
addresses. Fixed this.
- The scope ID is not stored as part of the GID entries and must be
passed as an argument to "rdma_gid2ip()".
- Added new method to "struct ib_device" which returns a pointer to
the network interface which belongs to the given infiniband
device. This is needed to be able to get the scope ID for IPv6
addresses via the associated ethernet interface.
- Added convenience function, "rdma_get_ipv6_scope_id()", to get the
scope ID for IPv6 addresses.
- Implemented new "get_netdev" method for mlx4ib. Other IB controller
drivers which want to support IPv6 addresses needs to implement this
aswell.
- Bumped the FreeBSD version due to changing "struct ib_device".

Mellanox hardware driver(s):
- Properly name an inclusion guard
- Fix compile warnings regarding unsigned enums
- Add two new sysctl nodes
- Remove all empty linux header files
- Make an error printout more verbose
- Use "mod_delayed_work()" instead of
cancelling and starting a timeout.
- Implement more Linux scatterlist
functions.

interface, in the r241616 a crutch was provided. It didn't work well, and
finally we decided that it is time to break ABI and simply make if_baudrate
a 64-bit value. Meanwhile, the entire struct if_data was reviewed.
o Remove the if_baudrate_pf crutch.
o Make all fields of struct if_data fixed machine independent size. The
notion of data (packet counters, etc) are by no means MD. And it is a
bug that on amd64 we've got a 64-bit counters, while on i386 32-bit,
which at modern speeds overflow within a second.
This also removes quite a lot of COMPAT_FREEBSD32 code.
o Give 16 bit for the ifi_datalen field. This field was provided to
make future changes to if_data less ABI breaking. Unfortunately the
8 bit size of it had effectively limited sizeof if_data to 256 bytes.
o Give 32 bits to ifi_mtu and ifi_metric.
o Give 64 bits to the rest of fields, since they are counters.
__FreeBSD_version bumped.
