I think ESP_CONFIG3_TENB is for FAS100A and FASHME. The bug here is on 
ESP236 and FAS236, so ESP_CONFIG3_TBMS would be the relevant bit.

The bit gets set when ESP_CONFIG2_SCSI2ENAB gets set (as in David's 
patch) so we then need to avoid clobbering it, since ESP_CONFIG3_TBMS == 
ESP_CONFIG3_EWIDE. I think we have to test for HME to avoid this clash.
