Correct the formula for calculating the RQ page remainder,
which should be in byte granularity. The result will be
non-zero only for RQs smaller than PAGE_SIZE, as an RQ size
is a power of 2.
Divide this by the SQ stride (MLX5_SEND_WQE_BB) to get the
SQ offset in strides granularity.

bnxt_en: Bug fixes.
This short series fixes resource related logic in the driver, mostly
affecting the RDMA driver under corner cases.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
Currently, the driver adjusts the bp->hw_resc.max_cp_rings by the number
of MSIX vectors used by RDMA. There is one code path in open that needs
to check the true max_cp_rings including any used by RDMA. This code
is now checking for the reduced max_cp_rings which will fail when the
number of cp rings is very small.
To fix this in a clean way, we don't adjust max_cp_rings anymore.
Instead, we add a helper bnxt_get_max_func_cp_rings_for_en() to get the
reduced max_cp_rings when appropriate.

When the driver detects that resources have changed during open, it

init sequence to initialize the default rings again. We also need
to signal the RDMA driver to stop and clear its interrupts. We then
call the RoCE driver to restart if a new set of default rings is
successfully reserved.

Now in sctp_apply_peer_addr_params(), if SPP_IPV6_FLOWLABEL flag is set
and trans is NULL, it would use trans as the index variable to traverse
transport_addr_list, then trans is set as the last transport of it.
Later, if SPP_DSCP flag is set, it would enter into the wrong branch as
trans is actually an invalid reference.
So fix it by using a new index variable to traverse transport_addr_list
for both SPP_DSCP and SPP_IPV6_FLOWLABEL flags process.
