Subject: hw/net/rocker: Dubious code in tx_consume()
Date: Sat, 15 Feb 2020 14:15:22 +0100	[thread overview]
Message-ID: <63e927fd-a462-a871-fcd7-c54dac07173e@redhat.com> (raw)

Hi Jiri,

I am trying to understand this code Scott Feldman added in commit 
dc488f88806:

  157 static int tx_consume(Rocker *r, DescInfo *info)
  158 {
  ...
  212     if (tlvs[ROCKER_TLV_TX_TSO_MSS]) {
  213         tx_tso_mss = rocker_tlv_get_le16(tlvs[ROCKER_TLV_TX_TSO_MSS]);
  214     }
  ...
  252     if (iovcnt) {
  253         /* XXX perform Tx offloads */
  254         /* XXX   silence compiler for now */
  255         tx_l3_csum_off += tx_tso_mss = tx_tso_hdr_len = 0;
  256     }

Nobody complained TSO_MSS is not implemented during almost 5 years.
Can we remove this code?

Thanks,

Phil.
