Subject: RE: [PATCH 01/13] RDMA: Split the alloc_hw_stats() ops to port and device variants
Date: Mon, 17 May 2021 23:06:29 +0000 [thread overview]
Message-ID: <b6045737954e4279939669a1f229c835@intel.com> (raw)
In-Reply-To: <1-v1-34c90fa45f1c+3c7b0-port_sysfs_jgg@nvidia.com>
> Subject: [PATCH 01/13] RDMA: Split the alloc_hw_stats() ops to port and device
> variants
>
> This is being used to implement both the port and device global stats, which is
> causing some confusion in the drivers. For instance EFA and i40iw both seem to
> be misusing the device stats.
>
> Split it into two ops so drivers that don't support one or the other can leave the op
> NULL'd, making the calling code a little simpler to understand.
