Different compilers may optimise the enum type in different ways. This ensures
coherency when range checking the value of enums in ibcore.

1) Fail to resolve RDMA address if rtalloc1() returns the loopback
device, lo0, as the gateway interface. Currently RDMA loopback is
not supported.
2) Use ip_dev_find() and ip6_dev_find() to lookup network interfaces
with matching IPv4 and IPv6 addresses, respectivly.
3) In addr_resolve() make sure the "ifa" pointer is always set, also when
the "ifp" is NULL. Else a NULL pointer access might happen trying to
read from the "ifa" pointer later on.
4) In rdma_addr_find_dmac_by_grh() make sure the "bound_dev_if" field
gets set properly instead of passing the scope ID through the IPv6
socket address structure. This is more in line with upstream OFED
in Linux.
5) In rdma_addr_find_smac_by_sgid() there is no need to pass the
scope ID for IPv6. Either it is stored in the "bound_dev_if" field
or ip6_dev_find() will find the correct network device regardless
of the scope ID.

iWarp and RoCE in ibcore. The selection of RDMA_PS_TCP can not be used
to indicate iWarp protocol use. Backport the proper IB device
capabilities from Linux upstream to distinguish between iWarp and
RoCE. Only allocate the additional socket required for iWarp for RDMA
IDs when at least one iWarp device present. This resolves
interopability issues between iWarp and RoCE in ibcore

- 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".

The iWARP Connection Manager (CM) on FreeBSD creates a TCP socket to
represent an iWARP endpoint when the connection is over TCP. For
servers the current approach is to invoke create_listen callback for
each iWARP RNIC registered with the CM. This doesn't work too well for
INADDR_ANY because a listen on any TCP socket already notifies all
hardware TOEs/RNICs of the new listener. This patch fixes the server
side of things for FreeBSD. We've tried to keep all these modifications
in the iWARP/TCP specific parts of the OFED infrastructure as much as
possible.

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.

Update the OFED Infiniband core to the version supplied in Linux
version 3.7.
The update to OFED is nearly all additional defines and functions
with the exception of the addition of additional parameters to
ib_register_device() and the reg_user_mr callback.
In addition the ibcore (Infiniband core) and ipoib (IP over Infiniband)
have both been made into completely loadable modules to facilitate
testing of the OFED stack in FreeBSD.
Finally the Mellanox Infiniband drivers are now updated to the
latest version shipping with Linux 3.7.

- Stateful TCP offload drivers for Terminator 3 and 4 (T3 and T4) ASICs.
These are available as t3_tom and t4_tom modules that augment cxgb(4)
and cxgbe(4) respectively. The cxgb/cxgbe drivers continue to work as
usual with or without these extra features.
- iWARP driver for Terminator 3 ASIC (kernel verbs). T4 iWARP in the
works and will follow soon.
Build-tested with make universe.
30s overview
============
What interfaces support TCP offload? Look for TOE4 and/or TOE6 in the
capabilities of an interface:
# ifconfig -m | grep TOE
Enable/disable TCP offload on an interface (just like any other ifnet
capability):
# ifconfig cxgbe0 toe
# ifconfig cxgbe0 -toe
Which connections are offloaded? Look for toe4 and/or toe6 in the
output of netstat and sockstat:
# netstat -np tcp | grep toe
# sockstat -46c | grep toe
