NUMA statistics are maintained on the zone level for hits, misses, foreign
etc but nothing relies on them being perfectly accurate for functional
correctness. The counters are used by userspace to get a general overview
of a workloads NUMA behaviour but the page allocator incurs a high cost to

Mikrotik 10/25G NIC supports hw checksum verification on rx for
IP/IPv6 + TCP/UDP packets. HW checksum offload helps reduce host
cpu load.
This enables the csum offload specifically for Mikrotik 10/25G NIC

The new Mikrotik 10/25G NIC maintains compatibility with existing atl1c

This patch set adds support for reporting cards higher link speed, max-mtu,

The kernel has xmit_more facility that hints the networking driver xmit

A user could control that length and trigger a buffer overflow.
