Subject: [dpdk-stable] [PATCH v2 02/12] net/bnxt: free default completion ring before VF configuration
Date: Wed, 9 Oct 2019 18:41:43 -0700 [thread overview]
Message-ID: <20191010014153.64908-3-ajit.khaparde@broadcom.com> (raw)
In-Reply-To: <20191010014153.64908-1-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.
Fixes: 7bc8e9a227cc ("net/bnxt: support async link notification")
