There's no need to reset the gid table twice and we need to do it only
for Ethernet ports. Also, no need to actively scan ndetdevs since it's
being done immediatly after we register netdev notifiers.

When reading the IPv6 addresses from the net-device, make sure to

When Ethernet netdev is not present for a port (e.g. when the link
layer type of the port is InfiniBand) it's possible to dereference a
null pointer when we do netdevice scanning.
To fix that, we move a section of code that needs to run only when
netdev is present to a proper if () statement.

In debugging an application that receives -ENOMEM from ib_reg_mr(), I
found that ib_umem_get() can fail because the pinned_vm count has
wrapped causing it to always be larger than the lock limit even with
RLIMIT_MEMLOCK set to RLIM_INFINITY.
The wrapping of pinned_vm occurs because the process that calls
ib_reg_mr() will have its mm->pinned_vm count incremented. Later a
different process with a different mm_struct than the one that
allocated the ib_umem struct ends up releasing it which results in
decrementing the new processes mm->pinned_vm count past zero and
wrapping.
I'm not entirely sure what circumstances cause a different process to
release the ib_umem than the one that allocated it but the kernel
stack trace of the freeing process from my situation looks like the
following:
Call Trace:
[<ffffffff814d64b1>] dump_stack+0x19/0x1b
[<ffffffffa0b522a5>] ib_umem_release+0x1f5/0x200 [ib_core]

The following patch fixes the issue by storing the pid struct of the
process that calls ib_umem_get() so that ib_umem_release and/or
ib_umem_account() can properly decrement the pinned_vm count of the
correct mm_struct.

Currently, the parent interface keeps sending broadcast group join
requests even if p_key index 0 is invalid, which is possible/common in
virtualized environments where a VF has been probed to VM but the

software. This creates unnecessary noise on the fabric and in the
kernel logs:

The original code run the multicast task regardless of the actual
P_key value, which can be avoided. The fix is to re-init resources and
bring interface up only if P_key index 0 is valid either when starting
up or on PKEY_CHANGE event.
