When doing memcpy/memset of EQEs, we should use sizeof struct
mlx4_eqe as the base size and not caps.eqe_size which could be bigger.
If caps.eqe_size is bigger than the struct mlx4_eqe then we corrupt
data in the master context.
When using a 64 byte stride, the memcpy copied over 63 bytes to the
slave_eq structure. This resulted in copying over the entire eqe of
interest, including its ownership bit -- and also 31 bytes of garbage
into the next WQE in the slave EQ -- which did NOT include the ownership
bit (and therefore had no impact).
However, once the stride is increased to 128, we are overwriting the
ownership bits of *three* eqes in the slave_eq struct. This results
in an incorrect ownership bit for those eqes, which causes the eq to
seem to be full. The issue therefore surfaced only once 128-byte EQEs
started being used in SRIOV and (overarchitectures that have 128/256
byte cache-lines such as PPC) - e.g after commit 77507aa249
"net/mlx4_core: Enable CQE/EQE stride support".

Set the mcast loopback prevention bit in the QPC for ETH MLX QPs (not
RSS QPs), when the firmware supports this feature. In addition, all rx
ring QPs need to be updated in order not to enforce loopback checks.
This prevents getting packets we sent both from the network stack and
the HCA. Loopback prevention is done by comparing the counter indices of
the sent and receiving QPs. If they're equal, packets aren't
loopback-ed.
