The last patch which added support to extend the firmware shared
data to add channel data information has introduced a bug due to
the reserved space not adjusted accordingly.
This patch fixes the issue and also adds BUILD_BUG to avoid this
regression error.

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.

NPC transmit side mcam rules can use the pcifunc (in packet metadata
added by hardware) of transmitting device for mcam lookup similar to
the channel of receiving device at receive side.
The commit 18603683d766 ("octeontx2-af: Remove channel verification
while installing MCAM rules") removed the receive side channel
verification to save hardware MCAM filters while switching packets
across interfaces but missed removing transmit side checks.
This patch removes transmit side rules validation.

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

complement the 32 bit bitmaps in struct ethtool_eee with linkmode
bitmaps. Therefore, similar to ethtool_link_settings and
ethtool_link_ksettings, add a struct ethtool_keee. In a first step
it's an identical copy of ethtool_eee. This patch simply does a

During QoS scheduling testing with multiple strict priority flows, the
netdev tx watchdog timeout routine is invoked when a low priority QoS
queue doesn't get a chance to transmit the packets because other high
priority flows are completely subscribing the transmit link. The netdev
tx watchdog timeout routine will stop MAC RX and TX functionality in
otx2_stop() routine before cleanup of HW TX queues which results in SMQ
flush errors because the packets belonging to low priority queues will
never gets flushed since MAC TX is disabled. This patch fixes the issue
by re-enabling MAC TX to ensure the packets in HW pipeline gets flushed
properly.

Currently the NIX TX link credits are initialized based on the max frame
size that can be transmitted on a link but when the MTU is changed, the
NIX TX link credits are reprogrammed by the SW based on the new MTU value.
Since SMQ max packet length is programmed to max frame size by default,
there is a chance that NIX TX may stall while sending a max frame sized
packet on the link with insufficient credits to send the packet all at
once. This patch avoids stall issue by not changing the link credits
dynamically when the MTU is changed.
