Subject: [dpdk-dev] [PATCH 02/10] net/bnxt: free default completion ring before VF configuration
Date: Thu, 3 Oct 2019 22:02:38 -0700 [thread overview]
Message-ID: <20191004050246.90165-3-ajit.khaparde@broadcom.com> (raw)
In-Reply-To: <20191004050246.90165-1-ajit.khaparde@broadcom.com>
From: Santoshkumar Karanappa Rastapur <santosh.rastapur@broadcom.com>
If the VF resources need to be reconfigured using the
bnxt_hwrm_func_reserve_vf_resc, make sure that the default completion
ring is freed first before the resources are reserved.
Reallocate the ring once the VF resources are configured.
