[dpdk-dev] [PATCH v3 1/2] crypto/nitrox: fix invalid CSR register address generation

[Nagadheeraj Rottela <rnagadheeraj@marvell.com>]

If the NPS_PKT ring/port is greater than 8191 the NPS_PKT*() macros will
evaluate to incorrect values due to unintended sign extension from int
to unsigned long. To fix this, add UL suffix to the constants in these
macros. The same problem is with AQMQ_QSZX() macro also.

Coverity issue: 349899, 349905, 349911, 349921, 349923

Fixes: 32e4930d5a3b ("crypto/nitrox: add hardware queue management")
Fixes: 0a8fc2423bff ("crypto/nitrox: introduce Nitrox driver")
