[dpdk-dev] [PATCH v2] common/cnxk: align NPA stack to ROC cache line size

[Ashwin Sekhar T K <asekhar@marvell.com>]

Network Pool accelerator (NPA) is part of ROC (Rest Of Chip). So
NPA structures should be aligned to ROC Cache line size and not
CPU cache line size.

Non alignment of NPA stack to ROC cache line will result in
undefined runtime NPA behaviour.

Fixes: f765f5611240 ("common/cnxk: add NPA pool HW operations")
