====================
eth: bnxt: fix several bugs in the bnxt module
The first fixes setting incorrect skb->truesize.
When xdp-mb prog returns XDP_PASS, skb is allocated and initialized.
Currently, The truesize is calculated as BNXT_RX_PAGE_SIZE *
sinfo->nr_frags, but sinfo->nr_frags is flushed by napi_build_skb().
So, it stores sinfo before calling napi_build_skb() and then use it
for calculate truesize.
The second fixes kernel panic in the bnxt_queue_mem_alloc().
The bnxt_queue_mem_alloc() accesses rx ring descriptor.
rx ring descriptors are allocated when the interface is up and it's
freed when the interface is down.
So, if bnxt_queue_mem_alloc() is called when the interface is down,
kernel panic occurs.
This patch makes the bnxt_queue_mem_alloc() return -ENETDOWN if rx ring
descriptors are not allocated.
The third patch fixes kernel panic in the bnxt_queue_{start | stop}().
When a queue is restarted bnxt_queue_{start | stop}() are called.
These functions set MRU to 0 to stop packet flow and then to set up the
remaining things.
MRU variable is a member of vnic_info[] the first vnic_info is for
default and the second is for ntuple.
The first vnic_info is always allocated when interface is up, but the
second is allocated only when ntuple is enabled.
(ethtool -K eth0 ntuple <on | off>).
Currently, the bnxt_queue_{start | stop}() access
vnic_info[BNXT_VNIC_NTUPLE] regardless of whether ntuple is enabled or
not.
So kernel panic occurs.
This patch make the bnxt_queue_{start | stop}() use bp->nr_vnics instead
of BNXT_VNIC_NTUPLE.
The fourth patch fixes a warning due to checksum state.
The bnxt_rx_pkt() checks whether skb->ip_summed is not CHECKSUM_NONE
before updating ip_summed. if ip_summed is not CHECKSUM_NONE, it WARNS
about it. However, the bnxt_xdp_build_skb() is called in XDP-MB-PASS
path and it updates ip_summed earlier than bnxt_rx_pkt().
So, in the XDP-MB-PASS path, the bnxt_rx_pkt() always warns about
checksum.
Updating ip_summed at the bnxt_xdp_build_skb() is unnecessary and
duplicate, so it is removed.
The fifth patch fixes a kernel panic in the
bnxt_get_queue_stats{rx | tx}().
The bnxt_get_queue_stats{rx | tx}() callback functions are called when
a queue is resetting.
These internally access rx and tx rings without null check, but rings
are allocated and initialized when the interface is up.
So, these functions are called when the interface is down, it
occurs a kernel panic.
The sixth patch fixes memory leak in queue reset logic.
When a queue is resetting, tpa_info is allocated for the new queue and
tpa_info for an old queue is not used anymore.
So it should be freed, but not.
The seventh patch makes net_devmem_unbind_dmabuf() ignore -ENETDOWN.
When devmem socket is closed, net_devmem_unbind_dmabuf() is called to
unbind/release resources.
If interface is down, the driver returns -ENETDOWN.
The -ENETDOWN return value is not an actual error, because the interface
will release resources when the interface is down.
So, net_devmem_unbind_dmabuf() needs to ignore -ENETDOWN.
The last patch adds XDP testcases to
tools/testing/selftests/drivers/net/ping.py.

ping.py has 3 cases, test_v4, test_v6 and test_tcp.
But these cases are not executed on the XDP environment.
So, it adds XDP environment, existing tests(test_v4, test_v6, and
test_tcp) are executed too on the below XDP environment.
So, it adds XDP cases.
1. xdp-generic + single-buffer
2. xdp-generic + multi-buffer
3. xdp-native + single-buffer
4. xdp-native + multi-buffer
5. xdp-offload
It also makes test_{v4 | v6 | tcp} sending large size packets. this may
help to check whether multi-buffer is working or not.
Note that the physical interface may be down and then up when xdp is
attached or detached.
This takes some period to activate traffic. So sleep(10) is
added if the test interface is the physical interface.
netdevsim and veth type interfaces skip sleep.

When devmem socket is closed, netdev_rx_queue_restart() is called to
reset queue by the net_devmem_unbind_dmabuf(). But callback may return
-ENETDOWN if the interface is down because queues are already freed
when the interface is down so queue reset is not needed.
So, it should not warn if the return value is -ENETDOWN.

When the queue is reset, the bnxt_alloc_one_tpa_info() is called to
allocate tpa_info for the new queue.
And then the old queue's tpa_info should be removed by the
bnxt_free_one_tpa_info(), but it is not called.
So memory leak occurs.
It adds the bnxt_free_one_tpa_info() in the bnxt_queue_mem_free().

The bnxt_rx_pkt() updates ip_summed value at the end if checksum offload
is enabled.
When the XDP-MB program is attached and it returns XDP_PASS, the
bnxt_xdp_build_skb() is called to update skb_shared_info.
The main purpose of bnxt_xdp_build_skb() is to update skb_shared_info,
but it updates ip_summed value too if checksum offload is enabled.
This is actually duplicate work.
When the bnxt_rx_pkt() updates ip_summed value, it checks if ip_summed
is CHECKSUM_NONE or not.
It means that ip_summed should be CHECKSUM_NONE at this moment.
But ip_summed may already be updated to CHECKSUM_UNNECESSARY in the
XDP-MB-PASS path.
So the by skb_checksum_none_assert() WARNS about it.
This is duplicate work and updating ip_summed in the
bnxt_xdp_build_skb() is not needed.

When mb-xdp is set and return is XDP_PASS, packet is converted from
xdp_buff to sk_buff with xdp_update_skb_shared_info() in
bnxt_xdp_build_skb().
bnxt_xdp_build_skb() passes incorrect truesize argument to
xdp_update_skb_shared_info().
The truesize is calculated as BNXT_RX_PAGE_SIZE * sinfo->nr_frags but
the skb_shared_info was wiped by napi_build_skb() before.
So it stores sinfo->nr_frags before bnxt_xdp_build_skb() and use it
instead of getting skb_shared_info from xdp_get_shared_info_from_buff().

usb_control_msg() returns the number of transferred bytes or a negative
error code. The current implementation propagates the transferred byte
count, which is unintended. This affects code paths that assume a
boolean success/failure check, such as the EEPROM detection logic.
Fix this by ensuring lan78xx_read_reg() and lan78xx_write_reg() return
only 0 on success and preserve negative error codes.
This approach is consistent with existing usage, as the transferred byte
count is not explicitly checked elsewhere.

The first errata applicable to both RGMII and SGMII version

The workaround in this case is putting the PHY in managed mode and
applying a series of PHY writes before the link gest established.
The second errata applicable only to SGMII version of TJA1120 and

The workaround puts the SGMII PCS into power down mode and back up

ATU Load operations could fail silently if there's not enough space
on the device to hold the new entry. When this happens, the symptom
depends on the unknown flood settings. If unknown multicast flood is
disabled, the multicast packets are dropped when the ATU table is
full. If unknown multicast flood is enabled, the multicast packets
will be flooded to all ports. Either way, IGMP snooping is broken
when the ATU Load operation fails silently.
Do a Read-After-Write verification after each fdb/mdb add operation
to make sure that the operation was really successful, and return
-ENOSPC otherwise.

Currently on stable trees we have support for netmem/devmem RX but not
TX. It is not safe to forward/redirect an RX unreadable netmem packet
into the device's TX path, as the device may call dma-mapping APIs on
dma addrs that should not be passed to it.
Fix this by preventing the xmit of unreadable skbs.
Tested by configuring tc redirect:
sudo tc qdisc add dev eth1 ingress
sudo tc filter add dev eth1 ingress protocol ip prio 1 flower ip_proto \
tcp src_ip 192.168.1.12 action mirred egress redirect dev eth1

sco_conn refcount shall not be incremented a second time if the sk
already owns the refcount, so hold only when adding new chan.
Add sco_conn_hold() for clarity, as refcnt is never zero here due to the
sco_conn_add().
Fixes SCO socket shutdown not actually closing the SCO connection.
