With MTU sized receive buffers it is not expected to have CQE_RX
with multiple receive buffer pointers. But since same physcial link
is shared by PF and it's VFs, the max receive packet configured
at link could be morethan MTU. Hence there is a chance of receiving
plts morethan MTU which then gets DMA'ed into multiple buffers
and notified in a single CQE_RX. This patch treats such pkts as errors
and frees up receive buffers pointers back to hardware.
Also on the transmit side this patch sets SMQ MAXLEN to max value to avoid
HW length errors for the packets whose size > MTU, eg due to path MTU.

On OcteonTx2 silicon there two two types VFs, VFs that share the
physical link with their parent SR-IOV PF and the VFs which work
in pairs using internal HW loopback channels (LBK). Except for the
underlying Rx/Tx channel mapping from netdev functionality perspective
they are almost identical. This patch adds netdev driver support
for these VFs.
Unlike it's parent PF a VF cannot directly communicate with admin
function (AF) and it has to go through PF for the same. The mailbox
communication with AF works like 'VF <=> PF <=> AF'.
Also functionality wise VF and PF are identical, hence to avoid code
duplication PF driver's APIs are resued here for HW initialization,
packet handling etc etc ie almost everything. For VF driver to compile
as module exported few of the existing PF driver APIs.

When FLR is initiated for a VF (PCI function level reset),
the parent PF gets a interrupt. PF then sends a message to
admin function (AF), which then cleanups all resources attached
to that VF.
Also handled IRQs triggered when master enable bit is cleared
or set for VFs. This handler just clears the transaction pending
ie TRPEND bit.

Added 'sriov_configure' to enable/disable virtual functions (VFs).
Also added handling of mailbox messages from these VFs.
Admin function (AF) is the only one with all priviliges to configure
HW, alloc resources etc etc, PFs and it's VFs have to request AF
via mbox for all their needs. But unlike PFs, their VFs cannot
send a mbox request directly. A VF shares a mailbox region with
it's parent PF, so VF sends a mailbox msg to PF and then PF forwards
it to AF. Then AF after processing sends response to PF which it
again forwards to VF.
This patch adds support for this 'VF <=> PF <=> AF' mailbox
communication.

Problem:
TCP checksum in the output path is not being offloaded during GSO
in the following case:
The network driver does not support scatter-gather but supports
checksum offload with NETIF_F_HW_CSUM.
Cause:
skb_segment calls skb_copy_and_csum_bits if the network driver
does not announce NETIF_F_SG. It does not check if the driver
supports NETIF_F_HW_CSUM.
So for devices which might want to offload checksum but do not support SG
there is currently no way to do so if GSO is enabled.
Solution:
In skb_segment check if the network controller does checksum and if so
call skb_copy_bits instead of skb_copy_and_csum_bits.
Testing:
Without the patch, ran iperf TCP traffic with NETIF_F_HW_CSUM enabled
in the network driver. Observed the TCP checksum offload is not happening
since the skbs received by the driver in the output path have
skb->ip_summed set to CHECKSUM_NONE.
With the patch ran iperf TCP traffic and observed that TCP checksum
is being offloaded with skb->ip_summed set to CHECKSUM_PARTIAL.
Also tested with the patch by disabling NETIF_F_HW_CSUM in the driver
to cover the newly introduced if-else code path in skb_segment.

We have recently noticed that there is a case of lockless read/write to

while holding sk_callback_lock. Concurrently, tcp can access it. Usually to
read out the sk_prot pointer and invoke one of the ops,
sk->sk_prot->handler().
The lockless write (lockless in regard to concurrent reads) happens on the
following paths:
tcp_bpf_{recvmsg|sendmsg} / sock_map_unref
sk_psock_put
sk_psock_drop
sk_psock_restore_proto
WRITE_ONCE(sk->sk_prot, proto)
To prevent load/store tearing [1], and to make tooling aware of intentional

Don't assume the receive buffer size is a power-of-2 number of pages.
Instead, define the receive buffer size independently, and then
compute the page order from that size when needed.
This fixes a build problem that arises when the ARM64_PAGE_SHIFT
config option is set to have a page size greater than 4KB. The
problem was identified by Linux Kernel Functional Testing.
The IPA code basically assumed the page size to be 4KB. A larger page
size caused the receive buffer size to become correspondingly larger
(32KB or 128KB for ARM64_16K_PAGES and ARM64_64K_PAGES, respectively).
The receive buffer size is used to compute an "aggregation byte limit"
value that gets programmed into the hardware, and the large page sizes
caused that limit value to be too big to fit in a 5 bit field. This
triggered a BUILD_BUG_ON() call in ipa_endpoint_validate_build().
This fix causes a lot of receive buffer memory to be wasted if
system is configured for page size greater than 4KB. But such a
misguided configuration will now build successfully.
