Subject: Re: [PATCH net] sfc: fix TX channel offset when using legacy
 interrupts

> In legacy interrupt mode the tx_channel_offset was hardcoded to 1, but
> that's not correct if efx_sepparate_tx_channels is false. In that case,
> the offset is 0 because the tx queues are in the single existing channel
> at index 0, together with the rx queue.
