[dpdk-dev] [PATCH] net/bnxt: fix Rx queue pool calculation

[Ajit Khaparde]

When the number of Rx queues requested by the application is less than
the number of pools calculated, we end up calling HWRM_VNIC_ALLOC with
incorrect parameters. This causes the firmware to return an error.
Fix the Rx queue pool calculation.

Fixes: 10bb6ddc2984 ("net/bnxt: fix flow creation with non-consecutive group ids")
