octeontx2-pf: Use default max_active works instead of one

[ Upstream commit 7558ce0d974ced1dc07edc1197f750fe28c52e57 ]

Only one execution context for the workqueue used for PF and
VFs mailbox communication is incorrect since multiple works are
queued simultaneously by all the VFs and PF link UP messages.
Hence use default number of execution contexts by passing zero
as max_active to alloc_workqueue function. With this fix in place,
modify UP messages also to wait until completion.

octeontx2: Detect the mbox up or down message via register

[ Upstream commit a88e0f936ba9a301c78f6eacfd38737d003c130b ]

A single line of interrupt is used to receive up notifications
and down reply messages from AF to PF (similarly from PF to its VF).
PF acts as bridge and forwards VF messages to AF and sends respsones
back from AF to VF. When an async event like link event is received
by up message when PF is in middle of forwarding VF message then
mailbox errors occur because PF state machine is corrupted.
Since VF is a separate driver or VF driver can be in a VM it is
not possible to serialize from the start of communication at VF.
Hence to differentiate between type of messages at PF this patch makes
sender to set mbox data register with distinct values for up and down
messages. Sender also checks whether previous interrupt is received
before triggering current interrupt by waiting for mailbox data register
to become zero.

octeontx2-pf: Fix promisc mcam entry action

[ Upstream commit dbda436824ded8ef6a05bb82cd9baa8d42377a49 ]

Current implementation is such that, promisc mcam entry action
is set as multicast even when there are no trusted VFs. multicast
action causes the hardware to copy packet data, which reduces
the performance.

This patch fixes this issue by setting the promisc mcam entry action to
unicast instead of multicast when there are no trusted VFs. The same
change is made for the 'allmulti' mcam entry action.

octeontx2-pf: Restore TC ingress police rules when interface is up

[ Upstream commit fd7f98b2e12a3d96a92bde6640657ec7116f4372 ]

TC ingress policer rules depends on interface receive queue
contexts since the bandwidth profiles are attached to RQ
contexts. When an interface is brought down all the queue
contexts are freed. This in turn frees bandwidth profiles in
hardware causing ingress police rules non-functional after
the interface is brought up. Fix this by applying all the ingress
police rules config to hardware in otx2_open. Also allow
adding ingress rules only when interface is running
since no contexts exist for the interface when it is down.

octeontx2-pf: Fix page pool cache index corruption.

The access to page pool `cache' array and the `count' variable
is not locked. Page pool cache access is fine as long as there
is only one consumer per pool.

octeontx2 driver fills in rx buffers from page pool in NAPI context.
If system is stressed and could not allocate buffers, refiiling work
will be delegated to a delayed workqueue. This means that there are
two cosumers to the page pool cache.

Either workqueue or IRQ/NAPI can be run on other CPU. This will lead
to lock less access, hence corruption of cache pool indexes.

To fix this issue, NAPI is rescheduled from workqueue context to refill
rx buffers.
