[PATCH for-next 17/17] RDMA/bnxt_re: optimize the parameters passed to helper functions

[Selvin Xavier <selvin.xavier@broadcom.com>]

[-- Attachment #1: Type: text/plain, Size: 7465 bytes --]

From: Kashyap Desai <kashyap.desai@broadcom.com>

Avoid passing arguments like Opcode which can be retrieved from
bnxt_qplib_crsqe structure.
