[PATCH v3] net/ice: add NEON-optimised Rx/Tx vector paths

[Jay Wang]

Hi Bruce,

I think it would be better to restrict compilation of the vectorised paths to AArch64 only. 
So, rather than modifying the intrinsics as I proposed earlier, I added an extra check in the meson build configuration file, as shown in the following code snippet.
Could you please help verify the patch again? I also did a sanity check by cross building DPDK for AArch32 on my local AArch64 machine, and the file was not compiled, so no build errors were reported.

Sorry for duplicating the previous patches on the website. I've marked them as superseded.

Thanks,
Jay Wang
