Add resource pools and accessor functions. These pools can be queried by
the driver, whenever a finite resource is required. Some resources can
be reused, in which case an index and a reference count is used to keep
track of users.

If an SQ is deactivated and reactivated again, some packets could be
sent after MLX5E_SQ_STATE_ENABLED is cleared, but before
netif_tx_stop_queue, meaning that NAPI might miss some completions. In
order to handle them, make sure to trigger NAPI after SQ activation in
all cases where it can be relevant. Regular SQs, XDP SQs and XSK SQs are
good. Missing cases added: after recovery, after activating HTB SQs and
after activating PTP SQs.

Currently it can happen that an mqprio qdisc is installed with num_tc 8,
and this will reserve 8 (out of 8) TXQs for the network stack. Then we
can attach an XDP program, and this will crop 2 TXQs, leaving just 6 for
mqprio. That's not what the user requested, and we should fail it.
On the other hand, if mqprio isn't requested, we still give the 8 TXQs
to the network stack (with hashing among a single traffic class), but
then, cropping 2 TXQs for XDP is fine, because the user didn't
explicitly ask for any number of TXQs, so no expectations are violated.
Simply put, the logic that mqprio should impose a minimum number of TXQs
for the network never existed. Let's say (more or less arbitrarily) that
without mqprio, the driver expects a minimum number of TXQs equal to the
number of CPUs (on NXP LS1028A, that is either 1, or 2). And with mqprio,
mqprio gives the minimum required number of TXQs.

Since the blamed net-next commit, enetc_setup_xdp_prog() no longer goes
through enetc_open(), and therefore, the function which was supposed to
detect whether a BPF program exists (in order to crop some TX queues
from network stack usage), enetc_num_stack_tx_queues(), no longer gets
called.
We can move the netif_set_real_num_rx_queues() call to enetc_alloc_msix()
(probe time), since it is a runtime invariant. We can do the same thing
with netif_set_real_num_tx_queues(), and let enetc_reconfigure_xdp_cb()
explicitly recalculate and change the number of stack TX queues.

ice_vsi_cfg() is called from different contexts:
1) VSI exsist in HW, but it is reconfigured, because of changing queues
for example -> update instead of init should be used
2) VSI doesn't exsist, because rest has happened -> init command should
be sent
To support both cases pass boolean value which will store information
what type of command has to be sent to HW.

separate function. Create unroll functions for each part of
initialization, like: ice_init_dev() and ice_deinit_dev(). It
simplifies unrolling and can be used in remove flow.
Avoid freeing port info as it could be reused in reload path.
Will be freed in remove path since is allocated via devm_kzalloc().

When allocating the ICE_VSI_CTRL, the allocated struct ice_vsi pointer is
stored into the PF's pf->vsi array at a fixed location. This was
historically done on the basis that it could provide an O(1) lookup for the
special control VSI.
Since we store the ctrl_vsi_idx, we already have O(1) lookup regardless of
where in the array we store this VSI.
Simplify the logic in ice_vsi_alloc by using the same method of storing the
control VSI as other types of VSIs.

Main goal is to reuse the same functions in VSI config and rebuild
paths.
To do this split ice_vsi_setup into smaller pieces and reuse it during
rebuild.
ice_vsi_alloc() should only alloc memory, not set the default values
for VSI.
Move setting defaults to separate function. This will allow config of
already allocated VSI, for example in reload path.
The path is mostly moving code around without introducing new
functionality. Functions ice_vsi_cfg() and ice_vsi_decfg() were
added, but they are using code that already exist.
Use flag to pass information about VSI initialization during rebuild
instead of using boolean value.

Do few small cleanups:
1) Rename the function to reflect that it doesn't configure all things
related to VSI. ice_vsi_cfg_lan() better fits to what function is doing.
ice_vsi_cfg() can be use to name function that will configure whole VSI.
2) Remove unused ethtype field from VSI. There is no need to set
ethtype here, because it is never used.
3) Remove unnecessary check for ICE_VSI_CHNL. There is check for
ICE_VSI_CHNL in ice_vsi_get_qs, so there is no need to check it before
calling the function.
4) Simplify ice_vsi_alloc() call. There is no need to check the type of
VSI before calling ice_vsi_alloc(). For ICE_VSI_CHNL vf is always NULL
(ice_vsi_setup() is called with vf=NULL).
For ICE_VSI_VF or ICE_VSI_CTRL ch is always NULL and for other VSI types
ch and vf are always NULL.
5) Remove unnecessary call to ice_vsi_dis_irq(). ice_vsi_dis_irq() will
be called in ice_vsi_close() flow (ice_vsi_close() -> ice_vsi_down() ->
ice_vsi_dis_irq()). Remove unnecessary call.
6) Don't remove specific filters in release. All hw filters are removed
in ice_fltr_remove_alli(), which is always called in VSI release flow.
There is no need to remove only ethertype filters before calling
ice_fltr_remove_all().
7) Rename ice_vsi_clear() to ice_vsi_free(). As ice_vsi_clear() only
free memory allocated in ice_vsi_alloc() rename it to ice_vsi_free()
which better shows what function is doing.
8) Free coalesce param in rebuild. There is potential memory leak if
configuration of VSI lan fails. Free coalesce to avoid it.
