hw/net/rocker: Dubious code in tx_consume()

[Philippe Mathieu-Daudé]

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.
