Hi Ben,

Only bug fixes are backported to LTS. Not even new NIC drivers are backported.

We don't bump requirements for older LTS releases, so any change to minimum
required versions would only be for the 23.x series releases

I meant the atomics change set, I should have been clearer in that question, my apologies.  If the atomic work is planned to be backported, the question of if/when the C11 standard would be adopted seems less relevant since it would need to be supported for DPDK versions that do not have the C11 standard requirement too.
