[dpdk-stable] [PATCH v2] net/bnxt: fix rxq interrupt setting

[Ajit Khaparde]

[-- Attachment #1: Type: text/plain, Size: 1176 bytes --]

Don't set rxq interrupt config
Applications can set the rxq interrupt config to 1 or 0 as needed.
If an application is not interested in handling Rx interrupts and
prefers to poll Rx rings, there is no need for the PMD to set this
config option to 1.

Fixes: 1fe427fd08ee ("net/bnxt: support enable/disable interrupt")

v1->v2: Setting 0 or 1 in PMD would override application setting.  So skip it.
