From: Rasesh Mody Date: Wed, 20 Jul 2016 19:09:33 +0000 (-0700) Subject: net/bnx2x: disable fast path interrupts X-Git-Tag: spdx-start~6120 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=91b7e432bcef97e67147aa94aa5b9555b1beb16e;p=dpdk.git net/bnx2x: disable fast path interrupts Disable fastpath interrupts and remove unneeded delay in bnx2x_interrupt_action(). This patch fixes and prevents performance degradation (upto 50% drop) for BNX2X PMD.
