[02/10] net/bnxt: free default completion ring before VF configuration
Checks
Commit Message
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.
