Real number of Transmit queues are incremented when user enables HTB
class and vice versa. Depending on SKB priority driver returns transmit
queue (Txq). Transmit queues and Send queues are one-to-one mapped.
In few scenarios, Driver is returning transmit queue value which is
greater than real number of transmit queue and Stack detects this as
error and overwrites transmit queue value.
For example
user has added two classes and real number of queues are incremented
accordingly
- tc class add dev eth1 parent 1: classid 1:1 htb
rate 100Mbit ceil 100Mbit prio 1 quantum 1024
- tc class add dev eth1 parent 1: classid 1:2 htb
rate 100Mbit ceil 200Mbit prio 7 quantum 1024
now if user deletes the class with id 1:1, driver decrements the real
number of queues
- tc class del dev eth1 classid 1:1
But for the class with id 1:2, driver is returning transmit queue
value which is higher than real number of transmit queue leading
to below error
eth1 selects TX queue x, but real number of TX queues is x
This patch solves the problem by assigning deleted class transmit
queue/send queue to active class.

Simon reported that ndo_change_mtu() methods were never
updated to use WRITE_ONCE(dev->mtu, new_mtu) as hinted
in commit 501a90c94510 ("inet: protect against too small
mtu values.")
We read dev->mtu without holding RTNL in many places,
with READ_ONCE() annotations.
It is time to take care of ndo_change_mtu() methods
to use corresponding WRITE_ONCE()

According to GCC, the constriction of irq_name in otx2_open()
may, theoretically, be truncated.
This patch takes the approach of treating such a situation as an error
which it detects by making use of the return value of snprintf, which is
the total number of bytes, excluding the trailing '\0', that would have
been written.
Based on the approach taken to a similar problem in
commit 54b909436ede ("rtc: fix snprintf() checking in is_rtc_hctosys()")
Flagged by gcc-13 W=1 builds as:
.../otx2_pf.c:1933:58: warning: 'snprintf' output may be truncated before the last format character [-Wformat-truncation=]
1933 | snprintf(irq_name, NAME_SIZE, "%s-rxtx-%d", pf->netdev->name,

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.

AF reserves MCAM entries for each PF, VF present in the
system and populates the entry with DMAC and action with
default RSS so that basic packet I/O works. Since PF/VF is
not aware of the RSS action installed by AF, AF only fixup
the actions of the rules installed by PF/VF with corresponding
default RSS action. This worked well for rules installed by
PF/VF for features like RX VLAN offload and DMAC filters but
rules involving action like drop/forward to queue are also
getting modified by AF. Hence fix it by setting the default
RSS action only if requested by PF/VF.

verification to save hardware MCAM filters while switching packets
across interfaces but missed removing transmit side checks.
This patch removes transmit side rules validation.

kmalloc_array() without __GFP_ZERO flag does not initialize
memory to zero. This causes issues. Use kcalloc() for maps and
bitmap_zalloc() for bitmaps.

PCI device IDs of RVU device IDs are configurable and
RVU PF0's (ie AF's) are currently assumed as VFs that
identify loopback functionality ie LBKVFs. But in some
cases these VFs can be setup for different functionality.
Hence remove assumptions that AF's VFs are always LBK VFs
by renaming 'is_afvf' as 'is_lbkvf' explicitly and also
identify LBK VF using PCI dev ID. Similar change is done
for other VF types.

In current driver 64 BPIDs are reserved for LBK interfaces.
These bpids are 1-to-1 mapped to LBK interface channel numbers.
In some usecases one LBK interface required more than one
bpids and in some case they may not require at all.
These usescase can't be address with the current implementation
as it always reserves only one bpid per LBK channel.
This patch addresses this issue by creating free bpid pool from these
64 bpids instead of 1-to-1 mapping to the lbk channel.
Now based on usecase LBK interface can request a bpid using (bp_enable()).
This patch also reduces the number of bpids for cgx interfaces to 8
and adds proper error code

XDP queues are created/destroyed when a XDP program
is attached/detached. In current driver xdp_queues are not
getting destroyed on program exit due to incorrect xdp_queue
and tot_tx_queue count values.
This patch fixes the issue by setting tot_tx_queue and xdp_queue
count to correct values. It also fixes xdp.data_hard_start address.
