When qeth_flush_buffers() gets called for a group of TX buffers
(currently up to 2 for OSA-style devices), the code iterates over each
buffer for some final processing.
During this processing, it sets the TX IRQ marker on the leading buffer
rather than the last one. This can result in delayed TX completion of
the trailing buffers. So pull the IRQ marker code out of the loop, and
apply it to the final buffer.

The TX path usually maps the full content of a page into a buffer
element. But there's specific skb layouts (ie. linearized TSO skbs)
where the HW header (1) requires a separate buffer element, and (2) is
page-contiguous with the packet data that's mapped into the next buffer
element.
Flag such buffer elements accordingly, so that HW can optimize its data
access for them.

Current OSA models don't support TSO for traffic to local next-hops, and
some old models didn't offer TX CSO for such packets either.
So as part of .ndo_features_check, check if a packet's next-hop resides
on the same OSA Adapter. Opt out from affected HW offloads accordingly.

It's possible to have build configuration which will force PTP_1588_CLOCK=m
and so TI_K3_AM65_CPTS=m while still have TI_K3_AM65_CPSW_NUSS=y. This will
cause build failures:
aarch64-linux-gnu-ld: ../drivers/net/ethernet/ti/am65-cpsw-nuss.o: in function `am65_cpsw_init_cpts':
../drivers/net/ethernet/ti/am65-cpsw-nuss.c:1685: undefined reference to `am65_cpts_create'

relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `am65_cpts_create'
Fix it by adding dependencies from CPTS in TI_K3_AM65_CPSW_NUSS as below:
config TI_K3_AM65_CPSW_NUSS
...
depends on TI_K3_AM65_CPTS || !TI_K3_AM65_CPTS
Note. This will create below dependencies and for NFS boot + CPTS all of them
have to be built-in.
PTP_1588_CLOCK -> TI_K3_AM65_CPTS -> TI_K3_AM65_CPSW_NUSS
While here, clean up TI_K3_AM65_CPTS definition.

The log entries are triggered by either user configuration actions or

net: reduce dynamic lockdep keys
syzbot has been complaining about low MAX_LOCKDEP_KEYS for a
long time, it is mostly because we register 4 dynamic keys per
network device.
This patchset reduces the number of dynamic lockdep keys from
4 to 1 per netdev, by reverting to the previous static keys,
except for addr_list_lock which still has to be dynamic.
The second patch removes a bonding-specific key by the way.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
After commit b3e80d44f5b1
("bonding: fix lockdep warning in bond_get_stats()") the dynamic
key is no longer necessary, as we compute nest level at run-time.
So, we can just remove it to save some lockdep key entries.
Test commands:
ip link add bond0 type bond
ip link add bond1 type bond
ip link set bond0 master bond1
ip link set bond0 nomaster
ip link set bond1 master bond0
