Subject: Re: [PATCH net] net: bcmgenet: always enable status blocks

From: Doug Berger <opendmb@...il.com>
Date: Tue, 17 Mar 2020 17:05:36 -0700

> The hardware offloading of the NETIF_F_HW_CSUM and NETIF_F_RXCSUM
> features requires the use of Transmit Status Blocks before transmit
> frame data and Receive Status Blocks before receive frame data to
> carry the checksum information.
> 
> Unfortunately, these status blocks are currently only enabled when
> the NETIF_F_HW_CSUM feature is enabled. As a result NETIF_F_RXCSUM
> will not actually be offloaded to the hardware unless both it and

> configuration.

> This commit addresses this issue by always enabling the use of

> replaces the use of a dedicated flag within the driver private
> data structure with direct use of the netdev features flags.
