3a2c4d55e3 treewide: refresh kmalloc_obj() conversions
This is another run of the Coccinelle script for converting kmalloc()
family of allocations to kmalloc_obj() via the existing rules in
scripts/coccinelle/api/kmalloc_objs.cocci

This catches both the set of kmalloc() uses added since the first
kmalloc_obj() conversions in v7.0 and adds a large group missed in the
first pass due to Coccinelle not interacting well with the cleanup.h
scoped_...() family of macros[1]. I worked around this with spatch's
"--macro-file" argument to a file with all the scoped_...() macros mapped
to Coccinelle's YACFE_ITERATOR[2] as that was the closest viable control
flow indicator I could find.

Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc,
riscv, and s390 with no new warnings.

4e88fb3234 eea: introduce callback for ndo_get_stats64 and register netdev
This commit adds support for ndo_get_stats64 to provide accurate
interface statistics. With the TX and RX data paths now fully functional,
it is appropriate to register the netdevice and expose the interface to
userspace.

Registered the network device via register_netdev, and updated the
corresponding unregister_netdev and dev_close routines to ensure
synchronization.

aa8bca4cf2 eea: create/destroy rx,tx queues for netdevice open and stop
Add basic driver framework for the Alibaba Elastic Ethernet Adapter(EEA).

This commit introduces the implementation for the netdevice open and
stop.

This commit introduces HA to restore the device when error occurs,
but in HA scenarios the driver can't ensure to restore the status
correctly.
