The while loop after err_slaves should use post-decrement; otherwise
we'll fail to do the kfrees for i==0, and will run into out-of-bounds
accesses if the setup above failed already at i==0.
[I'm not sure why one even bothers populating the ->vlan_filter array:
mlx4.h isn't #included by anything outside
drivers/net/ethernet/mellanox/mlx4/, and "git grep -C2 -w vlan_filter
drivers/net/ethernet/mellanox/mlx4/" seems to suggest that the
vlan_filter elements aren't used at all.]

In the latest kernel, process_mad hook of the driver can be invoked as
soon as device is registered. In this hook, ocrdma driver is issuing a
command to get the stats counters from the HW. This is triggering system
crash since the statistics command resources are not allocated by the driver.
Changing the sequence of initialization to avoid this crash.

We are seeing this warning: at net/core/skbuff.c:4174
and before commit a44878d100 ("IB/ipoib: Use one linear skb in RX flow")
skb truesize was not being set when ipoib was using just one skb.
Removing this line avoids the warning when running tcp tests like iperf.

Older libraries that don't have all the new req_v2 fields
should be able to work as well. Today, if the library uses v2, it

the current.

The mlx5_ib driver supports the extended create_cq and create_qp user
verbs. In the current mechanism, a vendor supporting an extended uverb

Adding the actual support by setting the required bits in order to
support features like completion time-stamping and cross-channel.
