I'd have to check with DaveM, but such an assumption might in fact exist.
BTW, it would be nice to start CCing linux-scsi@xxxxxxxxxxxxxxx and
David S. Miller <davem@xxxxxxxxxxxxx> on future discussions.

Hello,
Does anyone have the register descriptions for the FAS216 chip? It would
seem that receiving only one byte during reconnect is perfectly normal
[1] unless SCSI-2 features are explicitly enabled (which esp_scsi
doesn't seem to be doing).
Also, looking at the timeout formulae in the old NCR53C9x.c driver, the
values would be different for FAS216. Why was this dropped from the
modern esp_scsi?
