[dpdk-stable] [PATCH 3/7] net/bnxt: fix receive interrupt vector

[Ajit Khaparde]

From: Stephen Hemminger <stephen@networkplumber.org>

The receive interrupt vector should be offset by the constant
RTE_INTR_VEC_RXTX_OFFSET; otherwise setting up some queue interrupts
will fail.

From: Rahul Gupta <rahul.gupta@broadcom.com>

Rearm will intimate hardware that current interrupts are processed
and it can continue to send more.
