In the past, the S/G format looked like: uint8_t address[4]; uint8_t datalen[3]; uint8_t spare; Through some firmware manipulation, that last byte, other than a flag bit, can be used as the 5th byte of the address. >Also- maybe it's time to start considering 64 bit PCI I'm hoping that being able to address 512GB will be enough for a while. I'd rather not expand the size of the S/G list members for address space no-one will be touching for the foreseeable future. -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
