ibcore: Mark write-only variables

Some LinuxKPI lock macros pass need a flags field passed in. This is
written to but never read from so gcc complains.

Fix this by marking the flags variables as unused to quieten the
compiler.

mlx4/OFED: replace the struct net_device with struct ifnet

Given all the code does operate on struct ifnet, the last step in this
longer series of changes now is to rename struct net_device to
struct ifnet (that is what it was defined to in the LinuxKPi code).
While mlx4 and OFED are "shared" code the decision was made years ago
to not write it based on the netdevice KPI but the native ifnet KPI
for most of it. This commit simply spells this out and with that
frees "struct netdevice" to be re-done on LinuxKPI to become a more
native/mixed implementation over time as needed by, e.g., wireless
drivers.

which need access to the macros.

Add support for IPv6 link local GIDs equal to the default GID for
VLANs in ibcore.

IPv6 link local addresses are usually derived from the netdev MAC
address. This is applicable to VLAN devices and its lower netdevice as
well. In such cases the IPv6 link local address is a duplicate of the
default GID.

Now that link local IPv6 addresses based GIDs are supported, allow
adding such GID entries in the GID table.
