PATCH 1/1 doc: update minimum supported kernel

The DPDK project is only committed to supporting upstream kernel versions that are still in support.
The 3.16 kernel has reached End Of Life (in June 2020). The next LTS kernel is 4.19 and is supported until December 2024.

This does not change the existing policy that distribution kernels that are older are still supported.

No objection, but I see 4.4 is the oldest LTS, and there are a few in the middle till 4.19 [1]. Is 4.19 selected specially?

And what about adding a note to say oldest LTS kernel version is supported?

Thanks Ferruh, I did not check before giving my ack. So I agree it should be 4.4.

Agree should be 4.4, I miss read one of the huge spreadsheets of releases. Wikipedia and kernel.org both say 4.4 is supported until Feb 2022.

So we need to support 4.4 through 22.02 release
