When exiting "for loop", the actual value of pi will be
increased by 1, which is compatible with the next calculation.
But when pi is equal to "ci + hr_cq-> ib_cq.cqe", the "break"
was called and the pi is actual value, it will lead one cqe
still existing, so the "==" should be modify to ">".

Send and Receive completion is handled on a single CPU selected at
the time each Completion Queue is allocated. Typically this is when
an initiator instantiates an RDMA transport, or when a target
accepts an RDMA connection.
Some ULPs cannot open a connection per CPU to spread completion
workload across available CPUs and MSI vectors. For such ULPs,
provide an API that allows the RDMA core to select a completion
vector based on the device's complement of available comp_vecs.
ULPs that invoke ib_alloc_cq() with only comp_vector 0 are converted
to use the new API so that their completion workloads interfere less
with each other.

Currently for PF and ECPF vports, representors are created before
their eswitch hardware ports are initialized in below flow.
mlx5_eswitch_enable()
esw_offloads_init()
esw_offloads_load_all_reps()
[..]
esw_enable_vport()
However for VFs, vports are initialized before creating their
respective netdev represnetors in event handling context.
Similarly while disabling eswitch, first hardware vports are disabled,
followed by destroying their representors.
Here while underlying vports gets destroyed but its respective user
facing netdevice can still exist on which user can continue to perform
more offload operations.
Instead, its more accurate to do
enable_eswitch switchdev mode:
1. perform FDB tables initialization
2. initialize hw vport
3. create and publish representor for this vport
disable_eswitch switchdev mode:
1. destroy user facing representor for the vport
2. disable hw vport
3. perform FDB tables cleanup

mc_promisc pointer points to an instance of struct esw_mc_addr allocated
as part of the esw structure.
Hence it cannot be NULL.
Removed such redundant check and assign where it is actually used.
While at it, add comment around legacy mode fields and move mc_promisc
close to other legacy mode structures to improve code redability.

vports needs to be enabled in switchdev and legacy mode.
In switchdev mode, vports should be enabled after initializing
the FDB tables and before creating their represntors so that
representor works on an initialized vport object.
Prepare a helper function which can be called when enabling either of
the eswitch modes.
Similarly, have disable vports helper function.

First enable TSAR Qos hardware block in device before enabling its
user vports.
This refactor is needed so that vports can be enabled before their
representor netdevice can be created.
While at it, esw_create_tsar() returns error code which was used only to
print error. However esw_create_tsar() already prints warning if it hits
an error.
Hence, remove the redundant warning.

Except bit toggling code, rest of the code is same to enable/disable
metadata passing functionality.
Hence, combine them to single function and control using enable flag.
Also instead of checking metadata supported at multiple places,
fold into the helper function.
